TopHomer Reduced Shank Drill Bit Set- 1/2” Shank Drill Bit, M35 HSS-Co Black and Gold Nitrided Finish, 135 Degree Split Point, Ideal for Wood, Plastic and Metal,Cutting Edge Diameter 63/64"

Feature: 【Parameter Information】Cutting angle 135°, shank diameter 1/2”, shank type tri-flat. Cutting edge diameter, cutting edge length and total length are different for each product. Check out the size chart for specific information. Please check the size you need before purchasing 【Reliable Material】This reduced shank drill bit is made of 63-65HRC HSS-Co, balancing hardness and impact resistance, with stable cutting edge wear resistance. The surface is treated with nitrided black and baked yellow to absorb lubricants and reduce drilling friction, suitable for wood, plastic and metal (such as stainless steel, aluminum, copper). It is recommended to evaluate the wear condition every 3-6 months for high-frequency use and replace it in time to maintain machining efficiency 【Tri-flat Shank Design】Tri-flat shank construction provides more efficient torque transfer and prevents bit slippage. 1/2” shank diameter of the heavy duty metal drilling is compatible with most industrial equipment (e.g., bench drills, milling machines) and is suitable for machining hard metals and automotive repair scenarios 【135° Opening Angle】135° opening angle with helical flute structure effectively guides debris away from the drill and reduces axial pressure during machining. This design of the woodworking drill bit reduces the probability of burrs on the hole edge and reduces operation fatigue, especially suitable for continuous drilling Specification: Name: Reduced Shank Drill Bit Material: HSS-Co Finish Type: Nitrided Black, Baked Yellow Model: A, B, C, D, E, F, G, H, J, K, L, M Cutting Angle: 135° Shank Diameter: 1/2” Cutting Edge Diameter:(Model A to M) 5/8", 43/64", 25/32", 61/64", 53/64", 31/32", 63/64", 29/32", 21/32", 7/8", 17/32", 19/32"(optional) Specific size information can be found in the size chart.

• 【Maintenance And Operation Recommendations】It is recommended to use cutting fluid when machining metal to reduce the cutting edge temperature and increase the life of the reduced shank twist drill bit. After use, it is recommended to remove debris immediately and wipe the shank and cutting edge with a soft cloth soaked in alcohol. If the cutting edge is found to be dull or cracked, it should be replaced promptly to avoid precision deviation or equipment damage
