Screw Machine Length Drill Bits, Drill Bit Size (Wire): #31 , Drill Bit Size (Decimal Inch): 0.1200 , Tool Material: Carbide , Cutting Direction: Right Hand MPN:4157800

The 1 inch cut diameter indexable end mill features a maximum depth of cut of 0.394 inches and an overall length of 5.51 inches for increased cutting capacity in hard materials such as steel or cast iron. The 1-inch shank diameter allows it to accommodate various tool holders, ensuring compatibility across diverse CNC machining centers or manual lathes. Its weldon shank enables simple clamping using ER collets or milling chucks without requiring adapters for a secure grip during cutting operations. Its square-shoulder design enhances rigidity against deflection, offering precise geometry with a high-helix primary angle of 25 degrees and an aggressive secondary angle of 30 degrees, providing versatility in chip evacuation or material removal at high feeds and speeds without chip breakout. As a result, it caters to machinists or fabricators seeking efficiency, accuracy, and durability in demanding cuts with reduced tool wear or breakage for prolonged service life in heavy-duty operations across industries ranging from automotive parts production to aircraft manufacturing.
