    Timberline 1/8" x 3-3/8" High-Speed Steel Drill Adapter with Taper Point Drill 1/3-3/8" Hex Shank, 608-266

    Description

    Timberline Drill Adapter For 1/8 Taper Point Work

    Timberline 1/8 x 3-3/8 drill adapter pairs a high speed steel drill with a 1/4 inch hex shank adapter, so you get a matched drilling setup that seats securely in standard driving tools. The drill is a taper point style, meaning the bit gradually tapers along its length to match the taper of the corresponding size screw, which helps form a seat that follows the screw profile. This 1/8 inch size is suited to jobs calling for that screw size, keeping the pilot path closely aligned with the fastener geometry. The adapter length of 3-3/8 inches provides reach while still fitting common chucks, helping you work in typical cabinet and woodworking situations.

    Job-Focused Details Of The Timberline Drill

    • The drill is made from high speed steel, which supports repeated drilling through typical woodworking materials while holding its cutting edge over many pilot holes.
    • A taper point drill geometry matches the taper of the corresponding size screw, guiding the screw into a shaped pilot that tracks straighter and seats more cleanly.
    • The 1/4 inch hex shank drill adapter locks into hex-style chucks, so the bit resists spinning under torque in quick-change, cordless, and standard drills.
    • The drill adapter length is 3-3/8 inches, giving working reach suitable for common furniture, cabinet, and fixture drilling tasks where access is moderate.
    • This bit can be used in any Quick-Change chuck, cordless and standard drills, and screw guns, which lets one setup move between drivers and drills without changing tools.

    Hex Shank Mounting And Taper Point Fit Details

    The Timberline 1/8 x 3-3/8 drill adapter uses a 1/4 inch hex shank drill adapter, so it sits positively in Quick-Change chucks that rely on a hex profile to control spin. That same hex shank also interfaces with cordless and standard drills and screw guns, keeping the bit stable under load in those tools. The drill itself is a taper point pattern matched to the corresponding size screw, so as the bit advances, it shapes a pilot that mirrors the screw core and taper, promoting consistent driving. Together, the shank interface and point geometry support steady pilot drilling followed by smooth screw installation on woodworking projects that use this 1/8 inch screw size.

    Using The Timberline 608-266 Drill In Woodworking

    Where This Taper Point Drill Adapter Performs Well

    This Timberline drill sits in the Bits, Blades and Cutters category under Boring and Drilling, identifying it as a drilling tool suited to making pilot holes. As a drill bit within the Drill Bits product class, it fills the pilot drilling role before screws are driven. The high speed steel construction works effectively in typical woodworking materials found in cabinet and general wood fabrication. Because the drill adapter has a 1/4 inch hex shank, it operates in Quick-Change chucks, cordless and standard drills, and screw guns, so the same 608-266 bit can follow your workflow across different tools on a bench or on site. The 1/8 inch taper point profile matches the corresponding size screw, supporting tasks that call for that pilot size.

    Why The Timberline Design Supports Repeatable Results

    The Timberline 608-266 combines a taper point drill with a 1/4 inch hex shank drill adapter, so every time it is used in a Quick-Change chuck, the bit seats to the same depth and orientation, controlling wobble and promoting straight holes. The taper of the drill matches the taper of the corresponding size screw, meaning the pilot shape is consistent from job to job, which helps screws start with less wandering and track down the center of the hole. High speed steel gives the cutting edges durability over many cycles, so the hole diameter stays closer to the intended 1/8 inch over extended use. Together, these details help installers and shop users repeat the same drilling and driving sequence across batches of work while using the same Timberline 1/8 x 3-3/8 drill adapter.
