Accupro 2500157 Roughing End Mill 1 in 5 Flute Solid Carbide

Product Description

The ACCUPRO 2500157 is a single-end roughing end mill engineered for aggressive material removal in CNC milling applications. Built from micrograin solid carbide and coated with TiCN (Titanium Carbonitride), it delivers high wear resistance and thermal stability during high-feed roughing passes. The cutter features a 1 inch mill diameter, 5 flutes, and a 2 inch length of cut with a 4 inch overall length. Right-hand cutting and right-hand flute direction are standard. This tool is used by machinists and tool-and-die professionals working on CNC vertical and horizontal machining centers.

This roughing end mill is suited for roughing operations in ferrous and non-ferrous materials where chip clearance and feed rate are priorities. The 5-flute geometry with TiCN coating handles steel, stainless steel, and cast iron applications in production shop environments. The regular-length configuration fits standard tool holders with a 1 inch shank diameter. It is a non-centercutting design, meaning plunge cutting is not recommended. Mill diameter tolerance is +0.000 to -0.005 inches and shank diameter tolerance is +0.0001 to -0.0004 inches, ensuring consistent fitment in precision toolholders.

Key Features

• Micrograin solid carbide construction for rigidity and long tool life
• TiCN coating increases surface hardness and reduces heat buildup at the cutting edge
• 5-flute design supports higher feed rates compared to 4-flute equivalents
• Right-hand cut and right-hand helix for standard CNC spindle compatibility
• 1 inch shank diameter with tight tolerance for secure toolholder engagement
• Non-centercutting geometry — not suitable for plunge or ramp entry without pilot hole

Compatibility

Designed as a direct-fit replacement for standard 1 inch shank roughing end mills used in CNC milling operations requiring regular-length, single-end solid carbide tooling.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Always power down and lock out the spindle before changing tooling. Seat the shank fully in a collet chuck or end mill holder and torque to the toolholder manufacturer specification. Confirm runout with a dial indicator before initiating a cut. Non-centercutting tools require a pre-drilled entry point or ramping strategy — do not plunge directly into material.
