## Summary description

STHOR 21705 drill bit, 100 mm length, supplied as a single piece. Designed for drilling operations compatible with standard drills and drill chucks. Suitable for general-purpose tasks where a 100 mm bit is required, including wood, construction materials, and repair jobs depending on drill type and bit material.

## Long description

STHOR 21705 drill bit, length 100 mm, single piece is a specialist bit designed for drilling through brittle materials such as glass, ceramics and porcelain. Supplied as one 100 mm long bit, it fits standard drills and chucks and is intended for tasks that require precise, clean holes without chipping when used with appropriate drill speed and cooling methods.
Advantages
The STHOR 21705 drill bit is manufactured from high-grade YG6X steel and features a hardened cutting geometry to maintain a sharp edge during repeated use. Its construction balances a very hard cutting blade with a tougher, more damage-resistant shank, reducing the risk of breakage or rapid dulling. The 100 mm length provides reach for deeper holes while remaining compatible with common hand and bench drills.
Suitable for
Drilling holes in glass panels and mirrors
Creating openings in ceramic tiles and sanitary ware
Porcelain drilling for fixtures and fittings
Repair and renovation tasks requiring clean, chip-free holes
Key specifications
Length: 100 mm
Material: YG6X high-grade steel

Supply: single piece
How to use
Secure the STHOR 21705 drill bit in a compatible drill chuck, ensuring it is properly centered and tightened. Use a slow to moderate drill speed and apply light, steady pressure to avoid overheating and prevent cracking of brittle materials. Use water or a cooling lubricant where appropriate to reduce heat and remove debris; start drilling at a shallow angle to form a guide point if necessary, then straighten to perpendicular as the hole begins. After completing the hole, remove the bit slowly and clear any remaining debris from the workpiece.
Usage recommendations
Use appropriate personal protective equipment such as safety glasses and gloves. For best results with glass and ceramics, secure the workpiece, use water cooling, and avoid excessive force. Match drill speed and feed to the specific material and thickness to minimize chipping and extend bit life.
