4 Spiral Flute Machine Reamer 4.25-5.78mm Solid Carbide Metal Cutter CNC for Metal Steel Tolerance Tool(5.55x30x60x4T)

4 Spiral Flute Machine Reamer 4.25-5.78mm Solid Carbide Metal Cutter CNC for Metal Steel Tolerance Tool 1 PieceSize: 7.91~12.09mm * 40mm * 75mm * 4 FLeuteLarge Core Diameter Design: Upgrade the cutting edge/groove/core diameter ratio, fatigue resistance, and chip flow smoothness. Excellent resistance to resistance and vibration, reducing tool breakageSuitable for Blind Hole Machining: Gou grooves are CNC machined, smooth chip removal resistance is smallHelical Groove Design: Large capacity chip discharge groove discharges smoothly High efficiency and high precisionChamfer Design: The handle has a chamfered design, making it easier to clampCarbide Material: Good toughness and high hardness. Hard tungsten steel alloy features high compatibility, high hardness, and high strength, ensuring smooth and fast cutting, making it a specialized milling cutter material for high-speed cutting applicationsBlade Nano Coating: The blade is coated with a nano-layer, which allows for direct rough to finish machining of materials heat-treated below 60°, reducing the number of tool changes and enhancing machine efficiency, thereby saving manufacturing timeApplicable Materials: Gray cast iron, die steel, alloy steel, tool steel, spring steel, quenched and tempered steel.Packing: 1 piece of Spiral Flute For Steel
