Timberline high speed steel drill adapter pairs a high-speed steel drill with a 1/4 inch hex shank adapter so you can drive tapered pilot holes using the same bit in standard, cordless, and quick-change setups. The taper of the drill matches the taper of the corresponding size screw, so the pilot hole follows the screw profile and supports cleaner driving. This 9/64 inch taper point layout keeps the shank sized for the screw body while easing chip removal during drilling. The 1/4 inch hex shank adapter seats solidly in quick-change chucks, helping the bit transfer torque without rounding the shank. Using a dedicated taper point drill like this reduces wandering at the start of the hole and supports straighter screw alignment through the workpiece.
The 1/4 inch hex shank adapter interface slots directly into any Quick-Change chuck, so the drill mounts quickly without spinning in the holder. That same hex shank also fits many cordless and standard drill chucks that accept 1/4 inch hex, simplifying tool changes between drilling and driving steps. Using a hex shank on the adapter improves grip in screw guns, helping maintain bit orientation as the screw enters the tapered pilot hole. The 9/64 inch taper point geometry works with the hex drive to keep the bit centered during drilling, supporting accurate hole placement before screws are driven.
This Timberline 9/64 inch taper point drill setup is designed for situations where a tapered pilot hole that tracks the screw profile is needed. Because the taper of the drill matches the taper of the corresponding size screw, it supports screw-driven joints that rely on the screw pulling parts together without splitting. In woodworking environments that use Quick-Change chucks, the 1/4 inch hex shank drill adapter lets this bit shift between drilling and driving roles without changing tools. The ability to run in cordless drills, standard drills, and screw guns means the same 608-268 assembly can move around the shop or jobsite while keeping pilot hole geometry consistent wherever screws of that size are used.
The high speed steel drill body delivers a stable cutting action, so each 9/64 inch taper point hole follows the same profile and supports repeatable screw engagement. The 1/4 inch hex shank on the drill adapter engages Quick-Change chucks and many hex-accepting drill chucks with positive drive, which helps prevent slippage that could widen the pilot. Because the taper of the drill matches the taper of the corresponding size screw, the screw threads cut progressively into the material, aiding controlled driving. Running the same Timberline 608-268 bit in screw guns as well as drills keeps the pilot and driving steps aligned around identical geometry, which reduces rework tied to mismatched hole sizing.
The Timberline 608-268 drill uses high speed steel, which supports repeated drilling in typical woodworking while maintaining the tapered cutting profile important for matching the screw.
The 1/4 inch hex shank drill adapter fits Quick-Change chucks, cordless drills, standard drills, and screw guns, so the same taper point bit can move quickly between tools without reconfiguring the setup.
The 9/64 inch taper point drill creates a tapered pilot hole whose taper matches the corresponding size screw, helping the screw follow the hole and seat with controlled driving.
This Timberline taper point drill is paired with a 1/4 inch hex shank drill adapter that works in any Quick-Change chuck, allowing fast bit changes during drilling operations.
The Timberline 608-268 taper point drill operates in Quick-Change chucks, cordless drills, standard drills, and screw guns, giving flexibility across common shop and jobsite tools.
The taper of the drill matches the taper of the corresponding size screw, so the screw advances progressively through the tapered pilot, supporting alignment and smoother seating.
The Timberline high speed steel drill adapter with 9/64 inch taper point drill combines a high speed steel body, a 1/4 inch hex shank adapter, and a screw-matched taper to support consistent tapered pilot holes. Because it runs in Quick-Change chucks, cordless drills, standard drills, and screw guns, it can stay in service across different stations while keeping screw geometry uniform. For woodworking and similar drilling where a tapered pilot matching the corresponding screw is required, the Timberline 608-268 configuration offers a focused solution that ties together mounting interface and hole profile.
