Added 5% cobalt to improve hardness and heat resistance. The Rockwell hardness is up to 67. It has a faster cutting speed and a longer service life, which is 12 times that of an average HSS bit; \u003cbr\u003e\n- [Accurate Card Position]:  Self-centering. The guiding separation point of the 135° rapid cutting is automatically centered and can be penetrated quickly under a small pressure. The straight shank can be firmly fixed and accurately centered, suitable for standard drill trays and conventional circular trays; \u003cbr\u003e\n- [Efficient and fast]: High-efficiency drilling can be carried out without walking. Remove debris and particles faster and easier; \u003cbr\u003e\n- [Low cost]: The lowest cost of drilling each hole. The solid cobalt steel drill bit can be reground; \u003cbr\u003e\n- [Split point]: You can drill directly to the required size without pre-drilling; \u003cbr\u003e\n- [Widely used]: Suitable for drilling stainless steel, copper cast iron, galvanized pipe, iron, aluminum alloy and other non-heat-treated metals whose hardness is less than HRC38. Not suitable for hardened steel\/high carbon steel. If it cannot penetrate, try to adjust the speed. \u003cbr\u003e\n  \u003cbr\u003e\nSpecifications: \u003cbr\u003e\nProduct Name: 99Pcs M35 Cobalt Twist Drill Bits Set ; \u003cbr\u003e\nMaterial:  HSS-Co M35 Cobalt; \u003cbr\u003e\nSize: \u003cbr\u003e\n16 Pcs x 1.5 mm, 16 Pcs x 2 mm, 15 Pcs x 2.5mm; \u003cbr\u003e\n10 Pcs x 3mm, 10 Pcs x 3.2mm, 8 Pcs x 3.5mm; \u003cbr\u003e\n8 Pcs x 4mm, 3 Pcs x 4.5mm, 3 Pcs x 5mm; \u003cbr\u003e\n2 Pcs x 5.5mm, 2 Pcs x 6mm, 2 Pcs x 6.5mm; \u003cbr\u003e\n2 Pcs x 8mm, 2 Pcs x 10mm; \u003cbr\u003e\n  \u003cbr\u003e\nMeasurement System: Metric; \u003cbr\u003e\nShank Type: Straight Shank; \u003cbr\u003e\nShank Shape: Round; \u003cbr\u003e\nQuantity: 99 Pcs × Drill Bits \u003cbr\u003e\n  \u003cbr\u003e\nNote: \u003cbr\u003e\nCobalt drill bits require slow RPM when drilling metals.
