Drill bit STHOR 23398, length 600 mm, single piece

STHOR 23398 is a 600 mm long drill bit supplied as a single piece, designed to provide extended reach for drilling deep or hard-to-access holes. The bit is intended for use with drills that accept long-format accessories and is suitable for tasks in construction, metalworking and carpentry where a standard-length bit would not reach. Its single-piece delivery simplifies inventory and selection when a long, rigid drilling tool is required.

Advantages

The 600 mm length enables drilling at greater depths or through thick materials without needing jointed extensions. Its design preserves alignment and stability during drilling to reduce wandering and ensure a straighter hole. Supplied as a single piece, the bit eliminates the need for couplers or multiple sections, providing a consistent drilling profile across the full length. The bit is compatible with standard drill chucks that accept long-format bits, allowing straightforward integration into common drilling setups.

Suitable for

• Drilling deep holes in wooden beams and structural timber
• Creating access or pass-through holes in renovation and installation work
• Drilling in metal sheets or profiles where extended reach is required
• Works in confined spaces where a longer reach avoids repositioning the drill

Key specifications

• Overall length: 600 mm
• Supply format: single piece
• Intended use: long-reach drilling in construction, metalworking and carpentry
• Compatibility: for drills that accept long-format drill bits and standard chucks

How to use

Select a drill with a chuck size and power rating appropriate for long-length bits and for the material to be drilled. Secure the STHOR 23398 bit in the drill chuck with adequate clamping force to prevent slippage. Mark the drilling position, start at low speed to establish the hole, then increase speed and apply steady, even pressure while maintaining alignment. Periodically withdraw the bit to clear chips and prevent overheating, especially when drilling dense materials. Follow standard safety practices including eye protection and secure workpiece clamping.

Usage recommendations

For best performance, use appropriate drill speeds for the material and allow frequent chip evacuation. When drilling metal, use cutting fluid to reduce heat and extend bit life. Check chuck tightness before each use and avoid lateral forces that can bend long bits.
