35/64 Inch Reduced Shank Twist Drill Bits M35 HSS Cobalt Drill Bits with 3/8" Shank for Stainless Steel Alloy Metal Drilling Tool

• Dimensions: Cutting Edge Diameter: 35/64 inch; Shank Diameter: 3/8 inch; Cutting Edge Length: 7.5 cm / 2.95 inches; Overall Length: 15.2 cm / 5.98 inches. Packaging: 1 piece
• High-Speed Steel: The reduced shank twist drill bit is forged from HSS-Co steel, providing a combination of hardness and toughness for wear resistance, offering high hardness, high-temperature resistance, fast cutting speed, and long service life
• 135° Point: The reduced shank twist drill features a 135° quick-cutting angle for rapid penetration, reducing pressure and ensuring precise positioning. This minimizes slipping and deflection during high-speed operations, reducing the likelihood of burr formation
• Black and Gold Coating: Premium gold titanium and black nitride dual coating can apply lubricant better for smoother drilling and is more durable and corrosion resistant. Spiral groove facilitates the export of metal chip, saving time and effort in operation
• Wide Application: Suitable for metal materials such as steel plates, aluminum, copper, and wood. The three-flat shank design ensures a tighter clamp, aiding in precise drilling

Feature: 【Hard and Sturdy】The reduced shank twist drill bit is made of HSS-Co high-performance steel forging, through the 63-65HRC Rockwell hardness tempering process, balancing the hardness of the edge and the toughness of the shank, in the continuous cutting of heat-conducting metals (such as stainless steel and alloy steel) can delay the softening of the edge to extend the cycle of continuous operation 【Anti-Rust and Corrosion Resistance】The black nitride and baked yellow treatment on the surface of this HSS-Co drilling bit improves wear resistance and also forms a dense oxidised layer, which slows down the risk of rust and corrosion in humid environments. In addition, its dark coating can also assist in observing the chip discharge status during operation. 【135° Open Angle Design】This 3-flats reduced shank twist drill's 135° drill tip angle design further optimises the cutting force distribution, making it more suitable for handling harder materials such as stainless steel and alloy steel plates than traditional drills. In addition, it can also effectively reduce the probability of burr generation at the drilling edge, while reducing the axial pressure of the drill bit when cutting to reduce operational fatigue. 【Easy to Use】The installation of this HSS-Co drilling bit is also very simple, you only need to insert the shank of the drill bit into the taper hole of the drill chuck or spindle, gently rotate to confirm the correct direction, and then use a spanner or special tool to lock it Specification: Material: HSS-Co Surface Treatment: Nitrided Black, Baked Yellow Length: 15.2cm/5.98in Shank Diameter: 3/8" Cutting Angle: 135° Note: Please allow for manual measurement errors. Package Included: 1 x M35 Reduced Shank Twist Drill Bit for Metal
