Accupro 14797562 Corner Radius End Mill 0.085in 4 Flute Carbide

Product Description

The ACCUPRO 14797562 is a solid carbide corner radius end mill designed for precision milling of small features and tight-tolerance profiles. With a 0.085 inch diameter, a 0.01 inch corner radius, and four right-hand spiral flutes, it produces smooth corner blends while reducing stress concentrations at the cutting edge. The micrograin carbide construction provides hardness and wear resistance suited to demanding cut conditions. At 1.5 inches overall length with a 0.255 inch length of cut, this single-end centercutting tool handles both plunge and peripheral milling operations in one setup.

This end mill is used in machining centers and CNC milling applications where small-diameter, close-tolerance work is required. The miniature series designation places it in high-precision tooling territory, making it a common choice for die and mold work, medical component machining, aerospace detail parts, and electronics fixtures. The bright uncoated finish is appropriate for non-ferrous materials and applications where coating build-up could affect dimensional accuracy on fine features.

Key Features

• 0.085 inch mill diameter with micrograin solid carbide construction for rigidity at small diameters
• 0.01 inch corner radius reduces stress concentration and improves surface finish at floor-to-wall transitions
• Four right-hand spiral flutes with centercutting capability for plunge entry and slot milling
• 30-degree helix angle promotes chip evacuation and reduces cutting forces
• Bright uncoated finish suitable for aluminum, brass, copper, and other non-ferrous materials
• Miniature series with 1/8 inch shank diameter fits standard collet toolholders common in high-speed spindles

Compatibility

Designed for use in CNC machining centers and manual mills equipped with 1/8 inch collet or end mill holders. Fits standard ER11, ER16, and similar collet systems accepting 1/8 inch shank tooling.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the 1/8 inch shank fully into the collet and tighten to the collet holder manufacturer specification. At small diameters, runout control is critical — check tool runout with a dial indicator before beginning the cut to avoid premature tool breakage.
