sourcing map Reduced Shank Drill Bit 29mm High Speed Steel HSS 4241 with 1/2 Inch Straight Shank

• High Speed Steel tool - 29mm cutting diameter. Good for most general purpose applications, featuring a combination of hardness and toughness for wear resistance.
• Reduced Shank - Expanding the size range capacity of a portable drill chuck. Common flute and overall length for minimal adjustment during tool changes.
• Polished Finish - Polished treatment adds lubricity. Small pockets on the surface of the tool that act to hold coolant near the cutting edge.
• Wide Application - Drill low and medium tensile strength materials, such aluminum, iron, copper, brass and metal. Reduced shank drill bit is widely suitable for wood processing. (Hardness of the material to be drilled should not exceed 29HRC.)
• Please Note: To make clean and precise holes, water is required for lubrication and cooling when drilling metals, and the feed speed should be controlled. Increased use of water lubrication will extend drill bit life.

Specification: Cutting diameter: 29 mm. 1/2" Shank Diameter Cutting edge length 74mm Effective cutting edge length 47mm Total length: 150 mm. Material: High Speed Steel 4241 (HSS 4241) Finish:Polished Shank Type:Round Shank Tool flute type: spiral. Hardened to: 62-63 HRC. Color: Silver Description: 1. The high speed steel tool is well suited for most general purpose applications, with a combination of hardness and toughness for wear resistance. 2. Reduced shank drill extends the size range of a portable drill chuck. Common flute and overall length for minimal adjustment when changing tools. 3. Polished treatment adds lubricity. Small pockets on the surface of the tool that keep coolant near the cutting edge. 4. Design for drilling in low and medium tensile strength materials such as aluminum, iron, copper, brass and metal. 5. Run counterclockwise (right cutting), spiral fluted tool removes chips up and out of the cut to reduce clogging. Package includes: 1 x Reduced Shank Drill Bit Instructions for use: 1. To make clean and precise holes, water is needed for lubrication and cooling when drilling metals. 2. Low drilling pressure and increased use of water lubrication extend the life of the drills.
