The 3/16" Sealey HSS Cobalt Drill Bit offers versatile performance for light to medium drilling applications in high carbon and stainless steel materials. This popular size is widely used across automotive, engineering, and general metalworking tasks where reliable hole-making in challenging materials is essential. Manufactured to DIN 338 specifications with fully ground construction, these drill bits feature 5% cobalt content that provides increased heat hardness, significantly extending tool life when working with tough materials.
The precision-engineered 135° split point is self-centring, helping to reduce thrust requirements and aiding easier material penetration with minimal drift. Optimised flute geometry delivers efficient, clog-free swarf clearance, maintaining consistent cutting performance. Each pack contains 10 drill bits supplied in a high-density storage case for protection and organisation.
The bits can be resharpened multiple times without compromising drilling performance, offering exceptional value for professional workshops and tradespeople.
