4-Flute Spiral End Mill Bits, 1 /2 inch Diameter 42mm Length, High Speed Steel Straight Milling Cutter with Storage Case- (Applications: for Plywood Hardwood Plastic),

Features

• Spiral End Mill Size --- Cutting Diameter: 1/2", Shank Diameter: 1/2", Cutting Length: 42mm / 1.65", Overall Length: 84mm / 3.31", Number of Flutes: 4
• Wide Applications --- Spiral end mills are suitable for wood, nylon, acrylic, resin, MDF, plywood, hardwood, and plastic. It can be used for slotting, profiling, cutting, milling, and sculpturing.
• Spiral Flute Design --- Facilitates efficient chip evacuation, reduces cutting forces, increases tool rigidity, and allows for better coolant flow to the cutting area. Sharp cutting edges provide smooth cuts without burrs for increased efficiency.
• High Speed Steel --- The milling bit is made of high-speed steel, with high hardness, heat resistance, wear resistance, and durability. HSS(High-Speed Steel) enables the drill body to harder and can keep a longer drilling life and fast drilling performance.
• Useful Tips --- Works with CNC milling machines, router machines, and engraving machines. Make sure the end mil is securely seated and tightened. Use an appropriate coolant or lubricant to enhance chip evacuation and heat dissipation.
