Harvey Tool 49810 Square End Mill 0.01 in 2 Flute Carbide

Product Description

The HARVEY TOOL 49810 is a miniature solid carbide square end mill designed for high-precision micro-machining applications. With a cutter diameter of 0.01 inches and a 3/64-inch (0.05 inches) length of cut, this tool is built for intricate detail work where tight tolerances are non-negotiable. The 1/8-inch shank diameter and 1.5-inch overall length make it compatible with standard collet systems used across a wide range of CNC machining centers. It features a right-hand cut, right-hand upcut flute geometry, a 20-degree helix angle, and a centercutting design that allows plunge entry. The bright, uncoated finish is suited to applications where coating buildup at micro scales would compromise dimensional accuracy. Licensed machinists and CNC operators working in tool-and-die, mold-making, or precision part manufacturing are the primary users of this type of end mill.

This end mill is intended for use in CNC milling operations that demand extreme precision at very small feature sizes. It is well-suited for engraving, slotting, profiling, and pocketing in metals, plastics, and composites where cutter diameter constraints are a primary design requirement. The two-flute geometry provides adequate chip clearance in fine-feature cuts. This tool is typically run at high spindle speeds with minimal depth of cut per pass, consistent with micro-machining best practices. Shops specializing in medical device components, aerospace precision parts, electronics enclosures, and mold cavities regularly employ tools in this diameter range.

Key Features

• 0.01-inch cutter diameter for micro-scale machining operations
• Solid carbide construction for rigidity and wear resistance at tight tolerances
• 2-flute upcut geometry with 20-degree helix angle for efficient chip evacuation
• Centercutting design allows direct plunge entry into workpiece material
• Right-hand cut and right-hand flute orientation for standard CNC spindle compatibility
• Bright, uncoated finish suitable for applications where coating thickness would affect dimensional results

Compatibility

Designed for use in CNC machining centers and high-speed spindles equipped with 1/8-inch collets or compatible tool-holding systems. No specific machine model compatibility was provided in the product data.

Installation Notes

Installation of micro-diameter end mills should be performed by a qualified machinist or CNC tooling technician. Ensure the spindle and collet are clean and free of debris before seating the 1/8-inch shank, as contamination at this scale can cause runout that immediately breaks the cutter. Power down the spindle and verify zero RPM before tool changes. Given the 0.01-inch diameter, even minor runout or improper collet torque can result in tool breakage, so verified low-runout toolholding is strongly recommended.
