Drill bit STHOR 23391, length 600 mm, single piece

STHOR 23391 is a single-piece drill bit with a 600 mm overall length designed for drilling tasks that require extended reach and deep-hole capability. Supplied as a single unit, this long drill bit is intended for use with compatible drills and appropriate chucks or holders. Its construction supports applications in construction, metalworking, and general-purpose drilling where a longer-than-standard bit is necessary.

Advantages

The single-piece design provides rigidity along the full length to reduce wobble and improve straightness during drilling. A 600 mm length allows access to recessed or deep workpieces without the need for extensions or special adapters. Supplied as one piece, the drill bit is ready for immediate installation and use with suitable drills. The straightforward design simplifies alignment and handling in both professional and DIY environments.

Suitable for

• Drilling deep holes in timber, soft metals and composite materials when used with the correct drill type
• Reaching fasteners or drilling points located in recessed or hard-to-access areas
• Construction, renovation and installation tasks requiring extended drilling reach

Key specifications

• Type: single-piece long drill bit
• Overall length: 600 mm
• Packaging: one piece per pack
• Intended use: for compatible electric drills and drill holders

How to use

Install the 600 mm drill bit into a drill with a chuck and capacity suitable for long bits, ensuring secure clamping to minimize flex. Select the appropriate drill speed and feed rate for the material being drilled; slower speeds and steady pressure are typically preferable for long bits to reduce vibration and heat build-up. Use coolant or periodic retraction if drilling metals to clear chips and manage temperature. After use, clean any chips from the flutes and store the bit in a protective holder to avoid damage or bending.

Usage recommendations

Verify compatibility with your drill and chuck capacity before use. For precision results, support the workpiece and consider pilot drilling if necessary. When drilling long holes in metal, use cutting fluid and allow the bit to cool periodically to extend tool life.
