Tools for CNC Woodworking

Bull-nose End-mill Ball-nose End-mill 1/4" 2-flute End-Mill Tool Family: MM204

Deep cutting end-mills optimized for shaping the sheet goods commonly used in the manufacture of dimensional signage, furniture and cabinetry. 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 bull-nose and ball cutters are intended for clean-up and fine surface finishing. All of the bits can be used as stand-alone cutters for single pass, high-speed cutting and shaping .

60° V-tipTool Families: EM2D8, EM2E8 & EM2E4

Designed specifically for the dimensional signage and engraving markets, 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 hardwood (maple, walnut, mahogany, cherry...) and softwoods 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 (±0.5°) permits either single-pass or multi-pass cutting without fear of steps or streaks

3-flute DeepReach Straight Wall End-mills - 3/16 in. Shank 3/16 in 3-flute long
Tool Family: MM3316

3-flute deep cutting end-mills designed for cutting hardwoods routinely used in musical instrument making and furniture fabrication. The flute geometry has been tuned to insure smooth cutting and low deflection under high chip loads.

Tapered carving tool Tool Families: CM204, CM304, CM404

The 1/4 in. shank and 1.00 in. depth of cut (DOC) in in the CM304 and CM404 families 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. The CM204 family features a 1.50 in. DOC for deeper cutting in HDU, WRC and other polular signage materials.

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.

O-flute Single Flute End-mills - 1/4 in. Shank Carbide O-flute 1-flute for softwoods and thermoplastics
For all plastics, woods and aluminum.
Tool Family: MP104

The "O" flute geometry introduced more than a decade ago is one of the most efficient flute designs for cutting thermoplastics that has yet been invented. With a high rake angle and relatively low helix, O-flute cutters manage to cut acrylic, polycarbonate, ABS, PVC and a host of other sheet polymers at very high chiploads without raising a burr or fracturing the edges of the kerf. All of this while leaving a remarkably clean surface finish. The real surprise is that this revolutionary geometry also works incredibly well in wood and aluminum.

4-flute Countersinks
1/8 in. shank, 1/4 in. head
4-flute carbide countersink
For all woods and wood products
Tool family: EM4E8

4-flute tools designed to produce chatter-free counter sunk holes with no edge fraying in most softwoods and hardwoods. The cutting edge geometry generates virtually zero lifting forces making the tools compatible with thin sheet goods.

Straight Wall Micro End-mills - 1/8 in. Shank
Diameters: 0.001 in. to 0.125 in. (0.025mm to 3.15mm)
Standard Length

This tool family combines large flute volumes and high-shear flute geometries to produce clean, chatter-free cuts in all woods and wood products. High feed-rates at moderate RPM (12K - 40K) offer significant productivity gains over conventional tooling.

2-flute End-mill Tool Family: MM208

High-rake 2-flute cutters optimized for cutting and shaping many softwoods and moderate hardness hardwoods. The flute geometry supports relatively high chip-loads and efficient swarf extraction.

3-flute Soft Media Cutter 3-flute End-mill
Tool Family: MM3I8

High-rake 3-flute cutters originally designed for cutting fret slots and inlay pockets in musical instruments. Deflection tolerant design supports high chip-loads and deeper cutting than 2-flute designs.

2-flute Ball-nose Soft Media Cutter Ball-nose End-mill
Tool Family: MM208

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.

3-flute Necked Soft Media Cutter 3-flute shell
Tool Family: MS3I8

Originally designed to meet the demands of cutting natural shell products like mother of pearl (MOP), conch and abalone, these tools have found widespread use in all aspects of precision inlay on musical instruments, custom pool cues, high-end cabinetry and custom furniture.

Deep Reach Straight Wall Micro End-mills - 1/8 in. Shank
Diameters: 0.001 in. to 0.125 in. (0.025mm to 3.15mm)
Extended Length

Utilizing the proven flute geometries, this family of tools feature aspect ratios (cutting length : cutting diameter) greater than 6 : 1. Large flute volumes and high-shear flute geometries produce clean, chatter-free cuts in all woods and wood products. They are specifically designed for applications that require deeper cutting than is possible with standard length tools.

Deep Reach 2-flute Soft Media Cutter 2-flt deep
Tool Family: MM208

High-rake 2-flute cutters optimized for cutting and shaping many softwoods and moderate hardness hardwoods. The flute geometry supports relatively high chip-loads and efficient swarf extraction.

Deep Reach 3-flute Soft Media Cutter 3-flt deep
Tool Family: MM308

High-rake 3-flute cutters designed for deep pocketing and cutting fret slots in radiused finger boards. Core design supports relatively high chip-loads with reduced deflection.
