Drill bit DeWalt DT90245-QZ, length 152 mm, single piece

DeWalt DT90245-QZ drill bit, 152 mm length, single piece, is a mid-length wood-boring bit engineered for general repair, construction and workshop use. It features a tri-flute tapered geometry and three cutting edges designed to improve chip evacuation and reduce binding during drilling. The full screw tip enables the bit to self-feed, helping maintain alignment and steady advance through timber. Supplied as one unit, this bit is compatible with standard drill chucks and quick-change hex systems.

Advantages

The tri-flute design combined with three cutting spurs promotes faster cutting and more efficient removal of wood chips, reducing clogging and allowing continuous operation with less effort. The full screw tip pulls the bit through the material for controlled penetration and cleaner holes. A quick-change compatible shank prevents unwanted spinning in hex adapters and extensions, simplifying bit changes and improving stability during repeated use.

Suitable for

• Drilling clean holes in soft and hardwoods for carpentry and joinery
• General repair and maintenance tasks requiring mid-length bits
• Workshop and on-site construction tasks where quick bit changes are needed
• Creating pilot and clearance holes for screws and fasteners

• Pack quantity: Single piece per pack

How to use

Install the bit in a compatible drill chuck or quick-change adapter, ensuring it is securely seated to prevent slipping. Start drilling at low speed to engage the full screw tip, which will draw the bit into the material; increase speed as appropriate for the material and hole size. Apply steady, even pressure and periodically withdraw the bit to clear chips if drilling deep holes. Use appropriate personal protective equipment, including eye and hearing protection, when operating power tools.

Usage recommendations

For optimal performance, use the bit with suitable speeds for the wood type being drilled and avoid excessive side loading. Regularly clear chips during extended drilling to maintain cutting efficiency and consider using a backing board when drilling through thin workpieces to reduce splintering.
