Package Content: 1pcs x Reduced Shank Drill Bit
Specification: Cutting Diameter:32mm/1.26"Shank diameter:12.7mm/0.5''br/>Total Length:150mm/5.91" Material : High Speed Steel 6542 (HSS 6542) Surface treatment:Nitriding treatment
Hardened to: 65-66 HRC
Cutting Edge Length: 70mm / 2.76" Color: Black
Description: 1.Black oxide treatment adds lubricity. Small pockets on the surface of the tool that act to hold coolant near the cutting edge. 2.High-speed steel tool is good for most general purpose applications, featuring a combination of hardness and toughness for wear resistance. 3.Running in a counterclockwise direction (right-hand cut), spiral fluted tool evacuates chips up and out of the cut to reduce clogging. 4.Reduced shank drill expand the size range capacity of a portable drill chuck. Common flute and overall length for minimal adjustment during tool changes.Design for drilling in low and medium tensile strength materials, such aluminum, iron, copper, brass and metal.
Note: 1.To make clean and precise holes, water is required for lubrication and cooling when drilling metals. The feed speed also should be controlled. 2. Low drill pressure and increased use of water lubrication will extend drill bit life.
