Tools for Makers of Fine Jewelry

Ever since we started making tools for cuemakers and luthiers, jewelers have been using some of our smaller end-mills and engraving tools to carve butter board and blue and green jeweler's wax. In response to the persistent demand for longer flute lengths on the smaller diameter mills, we have redesigned some of our existing tools and developed a few new ones. These high-aspect ratio micro-bits are part of our new DeepReach family of mold and sign making tools. 

Most of our 1/8" shank tools are available with and without depth setting rings.

DeepReach Fish-Tail End-mills

(butterboard, jeweler's wax, modeling wax, proofing plastic)

DeepReach High-Aspect-Ratio End-Mills (HAREM) have been tuned for deep cutting of butterboard and blue & green jeweler's wax.  Designed to accommodate high chip loads, all cutters in this family exhibit superior swarfe removal and low tip deflection.

Stub End-mills

Our 2-flute stub end-mills were designed specifically for cutting non-ferrous metals like copper, silver and gold.  The 4-flute tools are made for cutting brass, steel, sterling silver and stainless steel. They are characterized by low aspect ratio flute geometries insuring low deflection and long bit life at relatively high feed-rates. The precise radial relief reduces burr formation and chattering resulting in smoother, more uniform cutting.

Ball-nose End-mills

(hardwood, recon stone, stabilized wood, composites, non-ferrous metals)

The flutes of our ball-nose end-mills wrap around the tips of the tools with the identical geometry on the sides and across the ball.  This insures that the cutting properties (speed, feeds, smoothness, chip load) are the same at all points along the cut.

Drill Bits

(hardwood, recon stone, stabilized wood, composites)

Like all of our cutters, PreciseBIT solid carbide drills are  made using the finest grade Mitsubishi carbide. Sizes ranging from 0.008 in. (0.2mm) to 0.250 in. (6.35mm) are available from stock. Diameters down to 0.001 in. (25 micron) are available upon request.

ColletCare Spindle and Toolholder Cleaner / Lubricant

Designed by a corrosion chemist to:

  • dissolve varnish and gummy deposits in the spindle bore
  • loosen rust
  • inhibit corrosion

in spindle bores and on collets and toolholders.

Specialty Cutters

Over the years, we have found that certain materials place extraordinary demands on tool geometry.  This is especially true of shell, ivory, ebony and the rosewood family of hardwoods.  Their moisture content, oiliness, density and abrasiveness require that flute-shape, flute-volume, and helix angle be precisely tuned to achieve accurate cutting and acceptable tool life.

Ivory Cutting End-mill

Ivory, Horn and Tusk Cutter

(ivory, fossil ivory, horn, tusk)

The only 2-flute member of the UltraBit family, these 0.0313" (0.8mm) bits have been tuned for cutting ivory, horn and tusk.  The flute capacity has been increased to accommodate a wide range of moisture/oil content. The diameter is ground to within +/-0.0005"  (0.0127mm) insuring zero-glue-line inlay cutting. The best all-around 1/32" cutter that we make, this bit has become the general-purpose tool of choice for many cuemakers and luthiers for cutting rosewoods and other "gummy" materials.

Shell Cutter

Shell Cutter

(natural shell, Abalam , composites)

The 0.0313" (0.8mm) shell cutter features a 3-flute design with a light chip-breaker finish-grind that effectively, and accurately cuts away both natural and laminated shell.  A member of the UltraBit family, the shell cutter diameter is ground to within +/-0.0005"  (0.0127mm) insuring zero-glue-line inlay cutting and minimum material wastage.

Engraving / Scoring Bits

(hardwoods, shell, non-ferrous metals, mild steel)

PreciseBit thin-web (0.005", 0.127mm) "V" tip cutters combine fine line machining with the extra rigidity needed for high feed rates. Applications include scoring, marking, scrimshaw, and engraving.

Phenolic Backing Sheet

Tempered Phenolic Backing Sheets

Tempered Gold phenolic backing material is the perfect fixturing substrate for mounting delicate materials to be machined for inlay components. With a high degree of chemical resistance and excellent adhesion to common glues and adhesives (including hide glue and cyanoacrylates), Gold phenolic is compatible with the mounting requirements of virtually every material used by luthiers, jewelers, and pool cuemakers. The composition of the phenolic also acts to cool the tip of the drills and end-mills, extending tool life and eliminating thermal breakdown of the fixturing adhesive.
