Sealey HSS Cobalt Drill Bit

The 1/4" Sealey HSS Cobalt Drill Bit is ideal for medium-diameter drilling tasks in demanding materials, offering the perfect balance between hole size and structural strength. This size is particularly suited to general fabrication work, automotive repairs, and engineering applications where precision holes are required in high carbon or stainless steel components. Manufactured to DIN 338 standards with 5% cobalt content, this fully ground drill bit delivers exceptional heat hardness, significantly extending operational life compared to standard HSS alternatives. The 135° split point is self-centring, reducing thrust requirements and enabling easier penetration whilst minimising workpiece movement. Optimised flute geometry ensures efficient, clog-free swarf clearance throughout drilling operations. Supplied in a pack of 10 with a high-density storage case, these bits can be resharpened multiple times without affecting performance, providing outstanding long-term value for professional tradespeople and workshops.
