WICHEMI 10PCS TCT Hole Saw Kit Tungsten Carbide Tipped Hole Cutter Set Heavy Duty Hole Saw Hole Cutting Drill Bit for Stainless Steel Copper Iron Aluminum Iron Metal Plate 5/8\ to 2-1/8\ inch

...ial】- This hole saw is made from high quality tungsten carbide tipped cutters, ensures its high hardness, rust proof and wear resistance. Designed with precision ground, sharp tough gears and stepped pilot drill bit to drilling more precise, smooth, faster and safer, leave perfect cutting results..
【Fast Cutting Speed】- The spring-type guide drill can eject the chips to make the cutter body cut clean and smooth, which not only saves cleaning time, but also shortens the cutting time. The speed of burr-free holes is faster than that of traditional twist drills or other hole saws, and has a greater advantage in cutting time..
【Multipurpose Tools】TCT Drill Bit sets cut quick, precise holes in 28MM thickness metal material, they are industrial grade metal drilling hole cutter for stainless steel, mild steel, alloy steel, iron,copper, aluminum, castings, plastic and brass..
【Wide Application】: TCT Carbide Steel teeth for fast cutting of clean and smooth round holes. The carbide hole saws set are suitable for hand held electric drill, stand motor-driven drilling machine and mobile ribbon type magnetism drilling machine..

Bosch exclusive Turbo-Teeth technology for high speed performance and long life.
Specially shaped, large chip clearance slots for fast drilling, and easy plug removal.
High Carbon Steel construction designed for durability in applications with wood.
1/4-Inch hex shank for use in quick change chucks.

Cobalt Alloy Steel high speed steel for extended cutting edge life makes it ideal for drilling stainless steel.
Drills 12 different hole sizes, from 3/16" to 7/8" by 16ths.
SpeedPoint tip prevents "walking," gets fast starts, and eliminates the need for pilot/starting hole.
Single-flute cutting edge drills true round holes with smooth, clean finish.

【Main purpose】: Countersunk end mill is a specially manufactured tool, mainly used to cut holes that allow bolts or screw heads to be screwed into..
