Hss Drill Bits
JCB TurboJet HSS drill bits are built for precision drilling in metal, plastics and hardwoods. The TurboJet 7-point cutting edge tip starts cleanly without sliding and reduces walking on hard surfaces. Available in individual sizes from 2.5mm to 13mm and in sets, these bits deliver clean, accurate holes with minimum burring. Heat-resistant high-speed steel construction maintains edge sharpness through repeated use. Compatible with cordless and corded drill drivers.
Frequently Asked Questions
What makes the JCB TurboJet 7-point tip different?
The TurboJet 7-point cutting edge has multiple ground facets that bite immediately on contact, removing the need to centre-punch metal before drilling. The bits also include an M2 TiN coating that extends life up to four times versus standard HSS.
Can HSS drill bits be used on masonry?
No. HSS bits are designed for metal, wood and plastics. They will not penetrate masonry, brick or concrete effectively and will blunt immediately. Use tungsten carbide-tipped masonry bits for these materials.
How do I sharpen HSS drill bits?
HSS bits can be resharpened using a bench grinder or dedicated drill bit sharpener. Maintain the original point angle and ensure both cutting edges are equal length for a centred cut. For small bits, replacement is often more cost-effective than sharpening.
