NORTOOLS Drill Bit Sets 19 PCS M35 Cobalt 5% DIN338 Hss-G Metal Drill Set for Stainless Steel Alloy Steel 1.0-10mm x 0.5mm

Product description

• SPECIFICATION- 1-10mm x 0.5mm (19 PCS) DIN338, fully ground drills with 135 split point, amber finish
• MATERIAL- High-quality high speed steel containing Cobalt 5% (HSS M35 Cobalt 5%) are with excellent cutting performance, durability and hardness
• 135 SPLIT POINT- It should be used to cut hard steel materials and especially in deep holes over 4 times the drill diameter, cutting harder materials will produce thicker chips, minimizing work hardening of the cavity. The length of the lips on a 135 drill point, measured from the axis to the cuter corners, is relativity short. This enables quicker penetration into the work piece and reduces thrust and abrasion along the cutting edges
• APPLICATIONS- M35 HRC 63 67 cobalt drills are effective in drilling tough high tensile strength materials such as stainless steel. It is also suitable for cutting iron, alloy steel, sheet metals, non-ferrous metals, cast steel, plastic, etc
• PACKAGE- 19pcs M35 cobalt drill bit set with metal storage case which is durable for easy storage
