Frequently Asked Questions - GD 320 FESTOOL

How to adjust the guide plate?

Unscrew the knob (3.1) about 5 turns, lift the plate, rotate it to the hole corresponding to the drill bit diameter, then lower it onto the fixing pin. Retighten the knob. Make sure the plate is securely in place.

How to attach the drill to the stand?

If the drill has a 43 mm collar diameter, use the supplied reduction ring. Fit the ring with the slit facing the clamping screw. Place the drill in the guide collar and tighten the clamping screw (8.1) firmly.

How to limit drilling depth?

Use the two stop rings (7.1 and 7.2). The upper ring (7.1) prevents the drill bit from protruding too much (leave 5-10 mm between the tip and the plate). The lower ring (7.2) limits drilling depth. Adjust them and tighten the clamping screws.

How to use the parallel stop?

The parallel stop (2) guides the workpiece for precise drilling. It can be adjusted using a mark on the workpiece or the scale. Tighten the clamping screw (2.1) to secure it. For the GD 460 A model, the stop can also be adjusted perpendicularly.

How to tilt the stand (for GD 460 A)?

Loosen the two clamping nuts (16). Tilt the guide rods to the desired angle (between 90° and 45°). The angle is indicated on the scale (17). Adjust the indicator needle (18) and retighten the nuts. For safety, secure the base plate with clamping devices.

How to maintain the stand?

Regularly clean the guide rods with a cloth and lightly lubricate them with grease or machine oil. Keep the seating surfaces of the base plate clean. Clamping devices and fixing points must be free of chips. Use only original Festool spare parts.

What are the essential safety instructions?

Read all safety instructions before use. Hold the device firmly with both hands. Check that the chuck travel is not obstructed. Tighten all parts before drilling. Do not remove chips by hand. Unplug the drill before any adjustment or maintenance.

Can I drill without the guide plate?

Yes, for drill bits with diameter larger than 27 mm (up to 45 mm max), the guide plate can be removed. You must then work carefully and use the lower stop ring to avoid collisions between rotating parts and the workpiece.

What accessories are available?

Optional accessories: guide plate for odd-sized drill bits (ref. 621947), clamping devices (ref. 621949) to secure the stand, and clamping extensions (ref. 622471) for workpieces up to 300 mm. These accessories are not included in standard delivery.

i Advice or tip

3 Intended use

The drilling stands GD 320 and GD 460 are intended for precise drilling at the precise angle of 90°. By means of the guiding disk, it is possible to guide the spiral drills from dia. 8 to 26 mm, eventually, from dia. 6 to 27 mm, precisely and safely. Without a guiding disk, the maximum drilling depth is 45 mm. Two parallel stops server for a simple placement, or eventually, guiding on the material. The clamping elements for clamping the stand can be ordered as accessories. The stand can be employed with all electric drilling machines with the clamping neck of the dia. 57 or 43 mm that do not exceed the maximum torque of 75 Nm.

The drilling stand GD 460 A can be employed for drilling at an arbitrary angle in the range from 90° to 45°.

4 Safety Instructions

6 Bringing the Stand into Operation

6.1 Adjustment of the guiding disk

Choose the corresponding orifi ce in the guiding disk in compliance with the required drill diam-eter, and insert it into the axis of the drill (1.1):

▶ turn the rotary button (3.1) to the left through 5 revolutions approximately,
▶ lift the guide disk above the arresting pin,
▶ turn it to the required position and lower it back

upon the base board.

▶ Take care that the disk may engage with the locking pin.
▶ Retighten the rotary button (3.1).

6.2 Clamping of the drill

▶ Clamp the spiral drill into the chuck of the drilling machine, and tighten the chuck.
① It is allowed to employ only spiral drills of a length that does not exceed the indicated maximum drill length.

6.3 Clamping of the drilling machine

For the drilling machines with a clamping neck of the dia. of 43 mm, use a reducing ring.

▶ Situate the reducing ring in such a way that its notch may be directed to the clamping point [8.1] .
▶ Fit the drilling machine into the sleeve and tighten the clamping screw (8.1).

6.4 Adjustment of the drilling depth

▶ The upper limit of the stop is set up by means of the stop ring (7.1) and tightened with the clamping screw.
The position of the upper stop can be chosen in such a way that the drill may be directed by the guide ring, and the drill tip may be at a distance of 5 -10 mm from the surface of the base board.

In this way, you avoid a risk of damage to the drill or the material. The bottom stop ring (7.2) serves for limiting the drilling depth.

▶ Find out the required drilling depth by measuring or by a drilling test, and tighten the stop ring (7.2) under the sleeve.

The stop ring is of importance in particular if you are to drill several orifices of the same depth.

6.5 Additional handle

The additional handle (10) can be mounted in three positions according to choice (see the sketch). For the drills the torque of which exceeds 55 Nm, the extension piece (11) is employed. Always use the additional handle with the extension piece on the front side of the sleeve (see the picture).

6.6 Drilling with a parallel guide

Both the parallel guides (2) contribute to the safety of work. At the same time, they increase the precision and save time if it is necessary to drill more orifices at the same distance from the edge of the material. You can choose to use either one parallel guide at one side, or both the parallel guides at both the sides. The parallel guide is adjusted either to comply with the mark on the material (visual control according to the marking

(1.1) on the base board or with the scale on the parallel guide.

The parallel guide is then tightened in the required position by means of the clamping screw (2.1).
① With the tilting version, the ruler can be adjusted in the vertical direction (2.2) as well.

6.7 Adjustment of the angle of inclination (GD 460 A)

The tilting drilling stands (GD 460 A) allow for oblique drilling at the angles ranging from 90° to 45°. In perpendicular drilling, the indicator (18) on the scale (17) reads zero.

▶ Before the eventual adjustment of the angle of inclination, both the clamping nuts (16) are to be loosened.
▶ Now it is possible to tilt the guide bars to the required angle.
This angle can be ascertained on the scale (17) with an accurate division.
The indicator (18) is set to the required value of the scale, and then both the clamping nuts (16) are tightened again.

CAUTION: With the tilted drilling stand, the base board must be secured against sliding along the workpiece, because of safety reasons. The employment of the clamping elements (accessory) is an ideal way of fastening it.

6.8 Correction of the stop position (GD 460 A)

With the tilting drilling stands, the perpendicular position has been adjusted in the manufacturing plant by means of the stop screw (14).

If an additional adjustment of the set stop position is required, proceed in the following way:

▶ Loosen the securing nut (14.1) and the clamping nut (16).
▶ Bring the foot (15) to rest upon the head of the screw (14).
▶ Turning the stop screw in the required direction, you will change the angle to the required position.
▶ Tighten the securing nut (14.1) and the clamping nuts (16) again.
The indicator (18) can also be reset after having loosened the screw (19), and screwing it tightly again in the required position.

6.9 Clamping of the drilling stand

For the clamping of the stand upon the material, there serve the clamping elements (12). These can be fastened upon the base board (1).

▶ Insert the clamping element into the orifice

(1.4) from below, screw the clamping nut (12.1) upon it from above, and tighten it.
▶ By means of the screw (12.2), tighten it in the required position.

The clamping elements (not included in the scope of the delivery but accessories) are used always in pairs, from both the sides. We recommend employing four clamping elements.

For materials up to the maximum dimension of 300 mm, the clamping elements can be fastened on the bracket (13).

▶ Fit the screws (13.1) from below into the orifices in the base (1.4).
▶ Set the brackets upon the screws (13.1) from above, and tighten them with nuts (13.2).

The brackets (which are not included in the scope of the delivery, accessories) are offered in pairs (2 pcs). It is necessary to pay attention to the stand to be clamped on the beam between two clamps (12), situated on one bracket (the distribution of forces in the longitudinal sense of the bracket), not by means of two brackets (see the figure). The brackets have been designed in such a way that it might be possible to clamp them upon both the basic types of the stands (the vertical ones and the tilting ones) both in the longitudinal and the vertical directions.

7 Drilling

• Before you proceed to drilling, make sure that both the spiral drill and the drilling machine are well clamped.
• Check the stops and the guide disk, to see, whether they are set tightly, and if necessary, tighten the clamping elements.
• Do not work with blunt of damaged drills.
• During the drilling operation, hold the equipment always with both hands: one hand on the additional handle of the drilling stand, and the other hand on the handle and the switch of the drilling machine.
• The marking on the base board (1.2 and 1.3) serves for drilling with visual control according to the mark.

7.1 Guiding disk

For the spiral drills with even diameters, there is employed a guide disk which is included in the scope of the delivery. For the spiral drills with odd diameters, there is employed a guide disk with odd diameters, supplied as an accessory.

▶ For the replacement of the guide disk, unscrew the rotary button (3.1).
▶ Next, it is possible to remove the installed guide

disk and to install another one.

7.2 Drilling jobs without a guiding disk

For working with drills of a larger diameter than 27 mm (up to 45 mm as the maximum), the guide disk can be dismounted in compliance with the above procedure. According to necessity, it is possible to dismount also the springs (5), the stop tube (6) and the depth stops (7.1 and 7.2). In such a case, proceed with utmost care. In any case, we recommend employing the bottom stop ring (7.2) for protection against undesirable contact of the rotating parts with the material.

In particular, take care that the rotating parts of the drilling machine or the employed drills may not come into contact with the parts of the drilling stand.
