Tools for CNC Sign and Trophy Makers

Our tools are designed to machine virtually the entire set of materials commonly encountered when making 3D dimensional signs, side-lit displays and inlaid marquetry for flooring and chigh-end cabinetry.

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

The 1/4 in. shank and 1.00 in. depth of cut (DOC) in this tool family are designed for deep machining in large format dimensional signage as well as very detailed carving of architectural components, back-lit lithophanes and other decorative items.

Although the geometry of these tools was optimized for cutting and shaping hardwoods, they are equally at home machining plastics, phenolic composites, unfired ceramics and aluminum.

60° V-tip

Designed specifically for the dimensional signage and egraving markets, our 2-flute solid-carbide "V" cutters feature polished, high-rake cutting edges capable of producing a surface finish suitable for edge-lit transparent signs and plaques.

Edge finishes in HDU, hardwood (maple, walnut, mahogany, cherry...),softwoods, HDPE, POM (acetal) and phenolic composites are typically smooth and free of chatter.

High flute volume and precisely shaped ejection paths support high chiploads in a wide variety of sign making substrates. Precise "V" angle formation (±0.2°) permits either single-pass or multi-pass cutting without fear of steps or streaks.

1/4" Ball-nose End-mill 1/4" 2-flute End-mill (sign foam, sign board (HDU), gator board, red wood, WRC)

These tools are the first in a series of deep cutting end-mills optimized for shaping the sheet goods commonly used in the manufacture of dimensional signage. The flute geometry has been tuned to insure smooth cutting and low deflection under high chip loads.

Designed to work together, the fish tail bit is a high-performance roughing tool while the ball cutter is intended for clean-up and fine surface finishing. Nonetheless, both bits can be used as stand-alone cutters for single pass, high-speed cutting and shaping.

micrO-flute 2-flute End-mill

Combining large flute volumes and high-shear flute geometries, these tools produce clean, flash-free cuts in a variety of thermoplastics. High feed-rates at moderate RPM (12K - 40K) offer significant productivity gains over conventional tooling.

micrO-flute 1-Flute -  Designed specifically for high-speed cutting of thermoplastics. The fine finish produced by these tools make them the perfect choice for engraving edge-lit signs and contour cutting clear plastic appliques.

Fish-tail tip -  Primarily designed for through-cutting and contouring, the bits in this series can also be used for 3D roughing and clean out.

Ball-nose End-mill

The 1/8 in. dia. shank tools in this series have been optimized for single-pass and cleanup cutting in high resolution 3D carving applications where straight side walls are required.

ColletCare® Spindle and Toolholder Cleaner / Lubricant ColletCare spindle and tool-holder cleaner and lubricant

Designed by a corrosion chemist to:
· dissolve varnish and gummy deposits in the spindle bore
· loosen rust
