Engraving Plastic vs Wood: Which Cutter Kit to Use

Choosing between a 30° and 60° engraving cutter kit depends on your material and detail needs. This guide breaks down the decision rules for plastic and wood.
Quick Answer
For fine detail in plastic, choose a 30° engraving bit; for deeper, more visible cuts in wood, a 60° bit works better. Your shank size must match your router or CNC collet.
Angle Matters: 30° vs 60°
The bit angle controls the width and depth of the cut. A 30° engraving bit produces a narrower, sharper V-groove, ideal for fine lettering and intricate designs. A 60° engraving bit cuts a wider, more pronounced groove that stands out on wood surfaces.
Plastic tends to chip or melt with too aggressive a cut, so the 30° angle reduces stress on the material. Wood, being more forgiving, can handle the broader cut of a 60° bit without issue.
Shank Size and Tool Compatibility
Both 1/8" and 1/4" shanks are common, but your machine's collet determines which you can use. A 1/4" shank is stiffer and less prone to deflection, which helps maintain accuracy in deeper passes. A 1/8" shank is lighter and works well for fine detail work on softer materials.
If your CNC router accepts only 1/4" collets, the 60° kit with a 1/4" shank is your only option among these kits. For 1/8" collets, you can choose between the 30° and 60° kits.
Decision Rules for Choosing Your Engraving Cutter Kit
- Material First: If you engrave plastic (acrylic, polycarbonate, PVC), start with a 30° bit to minimize chipping and melting. If you engrave wood, a 60° bit gives a more visible, deeper groove. Match the angle to the material's behavior under cutting.
- Detail vs Visibility: For fine text, logos, or intricate patterns, the 30° bit produces crisp, narrow lines. For bold lettering or decorative cuts that need to stand out, the 60° bit creates a wider, more prominent V-groove.
- Collet Compatibility: Check your router or CNC spindle collet size. If it accepts only 1/4" shanks, choose the 60° kit (1/4" shank). If it accepts 1/8" shanks, you can use either the 30° or 60° kit in that shank size. Confirm your collet size before purchasing.
