Wood paddle drill bit GEKO 40 x 152 mm HEX for drilling large holes

Paddle (spade) drill bit GEKO 40 x 152 mm with a HEX shank is intended for drilling large-diameter holes in wood and wood-based materials. The bit has a 40 mm cutting diameter and a total length of 152 mm, providing the reach required for through-holes and deep boreholes in carpentry, timber framing and installation tasks. The HEX shank gives a positive grip in compatible chucks and allows quick bit changes when used with handheld drills and impact drivers that accept HEX bits.

Advantages

The flat paddle geometry and central point ensure fast chip removal and relatively clean hole edges when used at appropriate speeds. The 40 mm cutting diameter produces consistent large holes for dowels, pipe passages, and wiring. The HEX shank minimizes slipping in the drill chuck and improves torque transfer, which is useful when drilling dense softwoods or laminated boards. The overall length gives sufficient depth for most door and window installation jobs without needing extensions.

Suitable for

• Carpentry and timber framing
• Door and window installation
• Rough construction and site work
• Creating holes for conduits, pipes and large fasteners
• Drilling in softwood, hardwood and common wood-based panels

Key specifications

• Cutting diameter: 40 mm
• Total length: 152 mm
• Shank type: HEX
• Bit type: paddle / spade
• Compatible tool: handheld drills and impact drivers accepting HEX shanks

How to use

Insert the HEX shank firmly into the drill or impact driver chuck and tighten according to the tool manufacturer’s instructions. Mark the drilling position and, if required, use a center punch or an awl to prevent walking. Start drilling at low speed to engage the central point, then increase speed while applying steady, even pressure; maintain alignment to achieve a straight hole. Clear chips periodically by withdrawing the bit slightly or by using pecking motions on deep cuts. After finishing, retract the bit while the tool is still running briefly to clear remaining debris, then stop the drill before removing the bit.

Usage recommendations

For best results, use recommended drill speeds for the wood type: lower speeds for hardwoods and laminated materials, higher speeds for softwoods. Wear appropriate personal protective equipment, clamp the workpiece securely, and check that the drill or driver supports HEX shanks. Avoid excessive side pressure to reduce paddle breakage and maintain straight, clean holes.
