Feature(may vary by option.)
●Parameters: Material: HSS-6542; Hardened To: 65-66Hrc; Cutting Diameter: 27.5mm; Total Length: 155mm
●Material: high speed steel 6542 is designed to ensure sharp and fast execution in metal surfaces for clean results; 27.5mm cutting diameter Good for most general applications, with a combination of hardness and toughness for wear resistance
●Advantage: Expand the size range of the capacity of a portable drill chuck; common groove and total length for minimal adjustment during tool change
●Special design: the black oxide treatment ensures lubricity; small pockets on the surface of the tool, keep coolant close to the cutting edge
●Wide applications: design for drilling in materials with low and medium tensile strength, such as aluminium, iron, copper, brass and metal
[27.5mm]
Description
Auniwaig Drill Bit Reduced Shank
Box contents:
1 x Reduced Shank Drill Bit
Specification:
Cutting Diameter: 27.5mm
Total length: 155 mm.
Material: High Speed Steel 6542 (HSS 6542)
Surface treatment: nitriding treatment
Hardened to: 65-66 HRC
Cutting edge length: 70 mm.
Color: Black
Description:
1. Black oxide treatment adds lubricity. Small pockets on the surface of the tool that hold coolant near the cutting edge.
2. The high speed steel tool is well suited for most general purpose applications, with a combination of hardness and toughness for wear resistance.
3. Run counterclockwise (right-hand cutting), spiral fluted tool removes chips up and out of the cut to reduce blockages.
4. Reduced shank drill extends the size range of a portable drill chuck. Common groove and overall length for minimal adjustment when tool changes. Design for drilling in low and medium tensile strength materials, such as 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 should also be controlled.
2. Low drilling pressure and increased use of water lubrication extend the life of the drill bits.
