Harvey Tool Cutting Tools — Complete Product Guide
Summary
Harvey Tool is a specialty carbide end mill company headquartered in Rowley, Massachusetts, operating under the Harvey Performance Company umbrella. They don't compete with Kennametal or Sandvik on indexable inserts or turning — that's not their game. Harvey Tool's catalog is solid-carbide round tools in geometries that are hard or impossible to source from anyone else. Micro end mills down to 0.005" diameter, keyseat cutters in dozens of width-and-diameter combinations, back deburring tools, dovetail cutters, double angle shank cutters, and chamfer mills in angles most manufacturers don't bother with.
In US job-shop machinist surveys, Harvey Tool consistently comes up as the #1 specialty end mill brand. That reputation is built on three things: breadth of catalog, in-stock availability, and same-day shipping from their Rowley warehouse. If you need a 0.030"-wide keyseat cutter at 2 PM on a Tuesday, Harvey Tool is the realistic answer. A distributor catalog is not.
Sister brands under Harvey Performance Company: Helical Solutions (high-performance general-purpose end mills), Micro 100 (turning inserts, boring bars, grooving tools), Titan USA (tap and drill), CoreHog (roughing and core drilling). Helical handles the high-performance general-purpose side; Harvey Tool handles the weird shapes.
What Harvey Tool is best for
- Miniature work — anything sub-1/8" diameter where you need a specialty form. 0.005" ball end mills, 0.010" square end mills, extended-reach micro tools.
- Keyseat cutters — their catalog covers widths from 0.030" to over 1" in multiple shank sizes and arbor configurations. More combinations than anyone else stocking in the US.
- Undercut end mills — lollipop geometry for undercutting ribs, slots, and pockets that a standard end mill can't reach.
- Chamfer mills — they stock angles like 20°, 25°, 30°, 35°, 45°, 60°, 82°, 90°, 100°, 120°. Not just the common ones. If you have a print calling for a 25° chamfer on an aerospace bracket, Harvey Tool probably has the tool.
- Back deburring tools — spring-loaded or fixed-geometry tools for deburring the back side of through-holes and pockets without flipping the part.
- Dovetail cutters — for dovetail slots, T-slot prep work, and fixture features. Multiple included angles.
Where Harvey Tool is weak: general-purpose milling at larger diameters. If you need a 1" four-flute end mill to hog aluminum, go to Helical Solutions (same company, optimized for that). Harvey Tool is the specialty catalog; Helical is the production workhorse.
Brand architecture
Harvey Tool's product line doesn't use a grade-naming system the way Kennametal or Sandvik does. The differentiation is by geometry family and coating.
Geometry families
- Miniature End Mills — square, ball, and corner-radius profiles from 0.005" up through about 1/4". Long-reach and stub variants. Multiple flute counts.
- Keyseat Cutters — straight-tooth and staggered-tooth. Width-on-diameter combos designed to match ANSI/ASME keyway standards. Shank diameters from 1/8" to 1".
- Undercutting End Mills (Lollipop) — spherical cutting head on a reduced-diameter neck. Used for undercutting, contouring, and accessing features behind a wall.
- Chamfer Mills — single-angle and double-angle variants. Harvey Tool's chamfer catalog is probably the deepest in the US market for odd angles.
- Dovetail Cutters — 45°, 60°, and other included angles. Right- and left-hand cutting available.
- Double Angle Shank Cutters — symmetric V-profile tools for V-grooves, engraving, and dovetail chamfers.
- Back Deburring Tools — spring-loaded designs that pivot past the back edge and shave the burr on withdrawal.
- Engraving Tools — sharp-pointed single-flute and multi-flute tools for engraving characters, logos, and part markings in metal.
Coating options
Harvey Tool offers two primary coatings across most of their product lines:
- AlTiN Nano — their standard high-performance coating. Multi-layer aluminum titanium nitride with a nano-composite structure. Targets steel, stainless, and harder alloys. Harder and smoother than standard AlTiN; better suited to dry or minimal-coolant cutting. This is what most shops are running on 4140 and stainless work.
- AlTiN Black Series — a premium dark-appearance AlTiN variant aimed at harder materials and higher-temperature applications. Marketed for hardened steels and abrasive materials where standard AlTiN starts to struggle.
- Uncoated — available on much of the catalog, particularly miniature tools where coating thickness becomes significant relative to tool diameter. For aluminum, copper, and other non-ferrous materials, uncoated is usually the right call.
Speeds and feeds baseline
Harvey Tool publishes application-specific speeds and feeds on their website for each tool, organized by material. These are the most accessible starting-point charts in the specialty tooling space — a notable advantage over competitors who bury data in PDFs.
Rough starting ranges for common applications:
| Tool type | Material | Surface speed | Notes |
|---|---|---|---|
| 1/8" 4-flute end mill, AlTiN Nano | 4140 annealed | 250–400 SFM | Verify on Harvey's web chart |
| 1/8" 4-flute end mill, uncoated | 6061-T6 aluminum | 800–1500 SFM | Flood or air blast |
| Keyseat cutter, AlTiN Nano | 4140 / 17-4 | 150–300 SFM | Reduce on full-width cuts |
| Chamfer mill | General use | Match end mill starting point for material | Light pass, verify finish |
For micro tools (sub-1/8"), surface speeds don't drop — RPM climbs to compensate. A 0.020" end mill in aluminum might run 40,000+ RPM on a high-speed spindle. Harvey's web calculator handles the unit conversions.
When to use Harvey Tool vs. alternatives
- vs. Helical Solutions: Same parent company. Helical is the choice for general-purpose end mills, particularly in aluminum, stainless, and titanium at production volumes. Harvey Tool is for any geometry that Helical's catalog doesn't cover — keyseat, undercut, chamfer, dovetail, micro.
- vs. OSG / Kyocera Unimerco: OSG and Kyocera make miniature tools and specialty profiles, but Harvey Tool's catalog depth and in-stock same-day availability beats them for most US job shops. OSG wins on taps and threading tools — different product.
- vs. Sandvik CoroMill Plura / Kennametal Harvi: Those are high-production solid-carbide lines targeting aerospace and volume work. They don't stock keyseat cutters in 32 different width combinations. Harvey Tool fills the gaps their catalogs leave.
- vs. generic offshore tooling: Harvey Tool costs more per tool. The catalog depth, coating quality, and the fact that you can order at midnight and have it Thursday morning justifies the premium for low-volume specialty features. Don't use them for the roughing passes.
