About this item
  • SPECIFICATION- 1.0-10.0 x 0.1mm (91 PCS) DIN338, fully ground drills with 135ºsplit point, amber finish。Professional-Grade for Hard & Soft Materials:Specially engineered for machining challenging materials like stainless steel, cast iron, titanium alloys, and hard plastics. The round shank design ensures compatibility with professional drilling equipment, while its robust construction also makes it effective for wood and softer materials, offering true versatility.
  • Premium 5% Cobalt M35 Steel for Ultimate Durability：Crafted from genuine 5% cobalt M35 high-speed steel with a hardness of 63 HRC, these bits offer exceptional performance. Their heat resistance, wear resistance, and resistance to chipping are up to 3 times higher than standard HSS drill bits, ensuring a dramatically extended service life under demanding conditions.
  • 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 -91 M35 cobalt drill bit kits, capable of handling various drilling tasks from basic to advanced. The accompanying durable metal storage box keeps your items organized, protected, and easy to carry.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
