Dormer A777 HSS-E Cobalt Jobber Drill Bits 7.8mm Pack of 10

Designed for demanding professional and industrial applications, the Dormer A777 HSS-E Cobalt Jobber Drill Bits deliver exceptional durability and cutting performance in high-stress environments. The premium 8% cobalt content provides superior heat resistance and wear life, making these bits ideal for drilling stainless steel, titanium, and other tough materials where standard HSS bits would dull quickly. Each 7.8mm bit features a 135-degree split point that enables self-centring and reduces walking, ensuring accurate hole placement without the need for a centre punch. The heavy-duty web construction adds strength and rigidity, reducing the risk of breakage under heavy feed rates. With a bright finish for reduced friction and improved chip evacuation, these drill bits maintain consistent cutting action throughout extended use. The jobber length offers excellent balance between reach and rigidity, suitable for most manual and machine drilling tasks. Pack of 10 provides reliable stock for ongoing work. Whether used in maintenance, fabrication, or production environments, the Dormer A777 range offers professional-grade performance and reliability.
