Description

Suitable for drilling stainless steel, hard metal, aluminum, copper, plastic and hardwood. The 3-step design enables accurate centering, suitable for woodworking operations requiring precision drilling. In addition, the cobalt design allows it to perform better in hardwood boreholes. Control the bit speed from 200 to 1000 RPM, making it easier to drill in stainless steel. High RPM does not improve drilling efficiency, but rather increases the heat between the bit and the workpiece, which may cause the bit to soften and the workpiece to harden. Drill bit diameter ≤5mm, speed (1000~700)5-10mm, speed (700~350)10-15mm, speed (350~203) use cutting fluid to make the drill bit more durable. Stainless steel tapping oil or engine oil is added to prevent the stainless steel from overheating and forming a very hard oxide layer 【5% COBALT TWIST DRILL BITS SET】Made from M35 Cobalt Steel with Molybdenum and Cobalt added to form a hardened alloy, can measure up to 67 Rockwell hardness, cut faster, last longer, and last longer than normal HSS drill bits 12 times. 【115PCS SAE DIRLL BITS SET】The set includes 29pcs Fractional Size:1/16” to 1/2” in 1/64th increments; 26pcs Letter Size: A To Z; 60pcs Numbered Size: #1 To #60.

  1. unfortunately, i did not receive the item as pictured on the listing. i contacted the seller, he was very responsive, i sent pictures of what i received. he sent a return shipping label so there was not cost to me. returned the item upon receiving the item back, seller issued a full refund. very honest seller and very helpful. well it all worked out. just wished the return went a bit faster so i did not have to follow up. but again i would not hesitate to buy from him again.. all worked out.
