About Harvey Tool
Specialty Miniature Carbide Cutting Tools for CNC PrecisionHarvey Performance Company
Harvey Tool, part of Harvey Performance Company, has provided specialty carbide cutting tools to the precision metalworking industry for over 30 years, building a catalog of more than 31,000 miniature and specialty cutting tools fully stocked and ready to ship. The company specializes in tools smaller than 0.25" that standard cutting-tool suppliers don't stock, filling a critical gap for dental implant manufacturers, aerospace component shops, medical device precision machining, and fine-detail prototyping.
The Harvey Tool product line includes miniature endmills (ball, corner radius, square), high-performance drills for pre-hardened steels and exotic alloys, specialized engraving cutters, thread mills, deburring cutters, tapered endmills, keyseat cutters, reamers, and application-specific geometry tools. All tools use premium carbide with proprietary edge geometries optimized for different materials (aluminum, titanium, stainless steel, cast iron, composites).
Harvey Tool's advantage is inventory depth—they maintain 10,000+ tools in stock at all times, eliminating the 4–8 week lead times typical of specialty cutting-tool orders. Each tool undergoes precision inspection and dynamically balanced to specification, critical for spindle speeds often exceeding 30,000 RPM.
Applications span implant component machining, precision aerospace fixtures, medical endoscope optics, fine electronics housings, and intricate mold inserts where surface finish, tool life, and reliability directly affect product performance. Harvey Tool also offers technical consultation on speeds, feeds, and tool selection to maximize tool life and part quality.
ChatMRO connects precision machinists and CNC programmers instantly with the exact Harvey Tool specialty cutting tool—specify material being machined, tool diameter, flute count, and desired surface finish, and our AI surfaces matching tools with speed/feed recommendations from our indexed 31,000-tool database and 30M+ overall component catalog.

Frequently asked questions
Why do miniature endmills cost more per unit than standard-size tools?
Miniature tools require precision CNC grinding with tighter tolerances, use more exotic edge geometries to compensate for size-related strength limits, and demand higher spindle speeds and rigidity to perform. Harvey's 31,000-tool inventory also reflects inventory carrying cost and faster product turnover. The higher per-unit cost is justified by elimination of lead times and improved first-pass success.
What spindle speed should I use for a 0.125" Harvey Tool endmill in aluminum?
Miniature endmills run at much higher speeds than standard tools—typically 15,000–30,000 RPM for aluminum at 0.125" diameter. Start conservative (12,000 RPM) and increase if chatter persists; high speed reduces cutting force and improves finish. Consult Harvey Tool's speed charts included with each product—speeds vary significantly by material and tool geometry.
Can Harvey Tool micro drills be used in manual hand drills or only in CNC?
Harvey Tool micro drills are designed for CNC spindles where rotation is precise and consistent. Hand-drill chucking runout easily exceeds tool diameter, and vibration causes breakage instantly. Always use CNC or precision drill-press equipment with quality chucks for drills under 0.25".
What's the most common cause of Harvey Tool endmill breakage on first use?
Incorrect spindle speed (usually too slow) and insufficient feed rate, which cause rubbing rather than cutting. Rubbing generates heat, dulls the edge, and causes vibration that breaks the delicate tool. Always use Harvey's recommended speeds/feeds and ensure your spindle can actually achieve the required RPM before ordering.
Are Harvey Tool engraving cutters suitable for sign and trophy work, or only precision machining?
Harvey makes specialized engraving tools for both precision CNC and manual engraving work—different tool geometries for each application. Confirm your equipment type when ordering. Precision CNC engraving tools are sharper and optimize edge angles for tight tolerances; manual engraving tools are more durable for general engraving depth.
