High Performance Solid Carbide Roughing End Mill 4 Flute HRC55 for Steel CNC Heavy Cutting
Boost material removal rates on HRC55 steel with our 4-Flute Solid Carbide Roughing End Mills. Durable wave-edge design for CNC heavy cutting. In stock now!
Product Function
Designed for aggressive material removal, our Tungsten Carbide Roughing End Mill (4 Flute) is the ultimate tool for the "roughing" stage of CNC machining. Unlike standard end mills, the specialized wave-edge (corn teeth) geometry breaks metal chips into smaller pieces. This significantly reduces cutting forces, minimizes vibration, and allows for deeper cuts and faster feed rates on hardened steel (up to HRC55), preparing the workpiece efficiently for the final finishing pass.
Product Features
- Material: Premium Micro-Grain Solid Tungsten Carbide for superior wear resistance.
- Coating: Advanced AlTiN/TiAlN coating specifically for high-heat resistance during heavy milling on HRC55 steel.
- Geometry: 4-Flute design with a coarse pitch wave profile to maximize chip evacuation and heat dissipation.
- Application: Ideal for side milling, slotting, and cavity machining in Carbon Steel, Alloy Steel, Cast Iron, and Tool Steel.
- Precision: h6 shank tolerance ensures stable clamping and reduced runout.

FAQ
Q: Can this roughing end mill be used on Aluminum?
A: It is not recommended. This tool is coated and designed for ferrous metals (Steel, Cast Iron). For Aluminum, please check our Uncoated 3-Flute Aluminum Roughers to prevent chip welding.
Q: What is the helix angle of this cutter?
A: The standard helix angle for our HRC55 roughing end mills is 35° or 45°, optimized for chip removal in hard steel.
Q: Do you offer OEM/ODM services?
A: Yes, we can laser mark your logo on the shank and customize packaging for bulk orders.
Q: What is the shipping time for the US/Europe?
A: For stock items, we use DHL/FedEx/UPS, which typically takes 3-7 business days.
