Tools for CNC Woodworking

It is common knowledge that, because wood is much softer than metal, it is therefore easier to machine. Unfortunately, like most such "common sense notions". this is only true for a very limited set of operations. Lopping off the end of a fir 2 X 4 on a table saw is indeed quite a bit easier than cutting off a piece of 2 X 4 steel rod stock. However, when it comes to precision shaping and carving, the variable properties of wood of any kind, make it far more challenging to work with than all but the most difficult metals. Applications like luthery, marquetry, cabinet making and custom pool cue fabrication demand a level of precision roughly equivalent to watch making, but using materials that simply do not want to be cut into precise, predictable shapes.

As you may have discovered, there is not much information on feeds and speeds (RPM) for wood working to be found on the internet. In our experience, what there is out there is, at best, not very reliable and at worst, pure hogwash. As CNC woodworkers have found since the beginning of automated wood machining, nothing beats empirically determining the best combination of RPM and feed rate for the material you are cutting. To that end, we developed the "Sweetspot Test". It really works and repays the time you spend by reducing bit breakage, improving cut quality and increasing the productivity of you cutting operation.

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

2-flute DeepReach Straight Wall End-mills - 1/4 in. Shank

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 ball cutter is intended for clean-up and fine surface finishing. Both bits can be used as stand-alone cutters for single pass, high-speed cutting and shaping .

3-flute DeepReach Straight Wall End-mills - 3/16 in. Shank

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 Ball-Nose 3D Carving Tools - 1/4 in. Shank

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.

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.


2-flt deep

 

Deep Reach 2-flute Soft Media Cutter

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

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.

Deep-Reach 2-flute Ball-nose (straight wall)

Tool Family: MM208

The tools in this series have been optimized for high resolution deep-relief 3D carving where straight side walls are required.

Deep-Reach 3-flute Ball-nose (straight wall)

Tool Family: MM308

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

4-flute Countersinks
1/8 in. shank, 1/4 in. head

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.

60° V-tip

V-Tip Carving and Engraving Tools - 1/4 in. Shank

Tool 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

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.

  micrO-flute

micrO-flute 1-Flute

Tool Families: MP103 & MP108

Originally designed for high-speed cutting of thermoplastics, the very high rake angle and large flute volume make this the perfect cutter for hard to cut very soft woods like balsa and cedar. These tools excel at cutting materials that tend to fray or chip during machining, which includes many softwoods and hardwoods.
