Drill bit STHOR 23419 — length 900 mm, single piece

The STHOR 23419 drill bit is a long, single-piece tool with a total length of 900 mm designed for drilling deep or hard-to-reach holes in wood and similar materials. Supplied as one unit, this straight shank bit is intended for use with compatible drills and extensions when extended reach is required on construction, installation or woodworking tasks. The design focuses on depth capability and stability during long-hole drilling while remaining compatible with standard drill chucks and extended drilling setups.

Advantages

The long 900 mm length allows access to deep cavities and through-holes without repeatedly repositioning the workpiece. Being a single-piece drill bit reduces the risk of play or misalignment between segments, improving concentricity and drill straightness over the full length. The bit is suitable for use with common drill types and extension systems, simplifying setup for extended-reach drilling jobs and reducing the need for multiple shorter bits and couplers.

Suitable for

• Drilling deep holes through timber beams and panels
• Creating passage holes for cables, pipes and conduits in walls and floors
• Installation tasks where long, straight holes are required
• Construction and carpentry projects needing extended reach

Key specifications

• Overall length: 900 mm
• Supply: single piece
• Intended materials: wood and similar construction materials
• Compatibility: standard drill chucks and extension setups (check chuck capacity before use)

How to use

Fit the drill bit securely in a drill or extension that accepts the bit shank diameter and check chuck tightness before operation. Mark the drilling point on the workpiece, align the bit perpendicular to the surface where a straight hole is required, and drill at a steady speed, using moderate feed pressure to avoid bending. Withdraw the bit periodically to clear chips when drilling deep holes. Use appropriate personal protective equipment and ensure the workpiece is properly supported or clamped to prevent movement.

Usage recommendations

Verify compatibility with your drill and any extension accessories prior to use; ensure the chuck can hold the shank securely along the required length. For best results in long-hole drilling, maintain steady speed, clear chips regularly, and support the workpiece to prevent deflection. Use hearing and eye protection and follow safe drilling practices.
