HSS Reduced Shank Drill Bit Ø18mm / PCE

Product

HSS reduced shank drill bit with an 18mm diameter, designed for precision drilling in metal materials. Suitable for use with standard drill chucks that accommodate reduced shanks.

Specifications

• Manufactured from High-Speed Steel (HSS), offering strong resistance to heat and wear during metal drilling operations
• Reduced shank design allows compatibility with standard drill chucks, even when the bit diameter exceeds the chuck capacity
• 18mm cutting diameter provides consistent, clean bore holes in a range of metallic workpieces
• Suitable for drilling mild steel, cast iron, aluminum, copper, and similar metals

Usage

Insert the reduced shank into a compatible drill chuck and secure firmly. Apply steady, controlled pressure while drilling at an appropriate speed for the target metal. Use cutting fluid when necessary to reduce heat buildup and extend bit longevity.

FAQ

1. What does "reduced shank" mean? — A reduced shank means the shank diameter is smaller than the cutting diameter, allowing the bit to fit into standard drill chucks that would otherwise not accommodate an 18mm bit.
2. What materials can this drill bit cut through? — It is designed primarily for metal drilling, including mild steel, aluminum, copper, and cast iron.
3. Should I use cutting fluid with this bit? — Yes, using cutting fluid or lubricant is recommended to reduce friction, dissipate heat, and extend the working life of the bit.
4. What drill speed is recommended for an 18mm HSS bit? — Lower RPM settings are generally recommended for larger diameter bits drilling into metal to avoid overheating and premature wear.
5. Is this bit compatible with a standard pillar drill or bench drill? — Yes, the reduced shank design makes it compatible with most standard drill chucks found on pillar drills, bench drills, and hand-held power drills.
