| High Light | 135 degree split point drill ，self centering drill bits ，precision metal drilling | ||
This industrial drill bit set is built for precision metal drilling operations where hole accuracy and positional stability directly affect product quality. Every bit features a 135-degree split point with a self-centering tip that engages the workpiece instantly, eliminating the walking and drifting that plague conventional chisel-edge drills. The result is clean, accurately positioned holes in steel, stainless steel, aluminum and other metals, with noticeably less thrust pressure required from the operator or machine.
Crafted from M2 high speed steel and heat treated to a hardness of HRC 63-65, these bits maintain their cutting geometry through demanding production cycles. The flute design has been optimized for industrial feeds and speeds, clearing chips rapidly so that heat is dissipated and the cutting edge stays cool. For machine shops, fabrication lines and maintenance departments, this set provides the repeatability and durability that professional metalworking demands.

This set excels in precision applications such as jig drilling, fixture building, die and mold maintenance, sheet metal fabrication and structural steel assembly. The self-centering tip is particularly valuable when drilling into curved surfaces, round stock and thin-gauge metal where a standard drill would skate off position. Machinists also appreciate the reduced need for center punching, which speeds up setup time on multi-hole patterns.
In addition to ferrous metals, the bits perform well on aluminum extrusions, brass, bronze and other non-ferrous alloys, making the kit a versatile asset for general machine shops and maintenance crews. When paired with appropriate cutting fluid, these bits achieve clean hole finishes and consistent diameters across large batch runs.
Packaging & Quality AssuranceThe set is supplied in a robust metal index case with pre-formed size slots, then packed in a reinforced export carton with foam protection. We also offer customized case printing, laser marking and private label programs for industrial distributors. Quality control includes 100% visual inspection, hardness verification and sample drilling tests on every production lot.
Our factory specializes in high speed steel cutting tools and has supplied industrial customers across Europe, North America and Southeast Asia. We provide competitive FOB and CIF quotations, flexible order quantities and responsive technical support. Contact us today to discuss your volume requirements and delivery schedule.
