Product Number: DB055CB
Drilling into high carbon steel or stainless steel with a standard HSS bit often results in premature wear, overheating, and poor penetration. The Sealey DB055CB resolves this with a fully ground HSS Cobalt drill bit manufactured to DIN 338. The 5% Cobalt content increases heat hardness, helping to extend the working life of the bit. The 135° split point is self-centring, reducing thrust and aiding easier penetration, while efficient clog-free swarf clearance keeps the flutes clear during use. Supplied in a high-density case for safe storage. Pack of 10, diameter 5.5mm.
