Product Description
The CMT 663.130.11 V-Groove and Folding CNC Bit is a high-performance CNC router cutter engineered for professionals who demand precision and versatility in V-groove routing, miter folding, signmaking, lettering, and chamfer edge work. Built on a foundation of super strength steel and fitted with a high-grade HWM reversible knife, this 130 deg. insert-style bit handles a wide range of panel materials - from chipboard and plywood to MDF and laminates - making it a reliable choice for CNC woodworking shops and sign fabrication environments alike.
Key Features
- 130 deg. V-Groove cutting angle - delivers clean, precise angled cuts suited for miter folding and V-groove panel work, reducing the need for secondary finishing operations.
- HWM reversible knife inserts - the high-grade, replaceable knives extend tool life and reduce operating costs; a higher-quality knife grade is also available for demanding laminated and MDF applications.
- Super strength steel body - provides the structural rigidity needed to maintain accurate geometry under repeated CNC router loads, supporting consistent cut quality over extended production runs.
- 20mm shank diameter - matches standard CNC router collet sizing for a secure, vibration-minimizing connection that promotes smooth, chatter-free cuts.
- 2-tooth (2-flute) configuration - balances chip clearance with feed rate capability, allowing efficient material removal in both solid wood panels and sheet goods.
- Right-hand (RH) rotation - compatible with the direction of rotation on standard CNC router spindles, ensuring correct engagement geometry for clean, controlled cutting.
- Multi-application design - one tool covers V-groove routing, signmaking, lettering, chamfering, and miter folding, reducing tool changeover time and expanding shop flexibility.
Why This Product
- The 130 deg. folding angle makes this bit a purpose-built solution for miter fold panel fabrication, allowing sheet material to be scored and folded cleanly without additional joining hardware - a significant time saver in cabinet and display production.
- Reversible HWM insert knives mean worn edges can be flipped or replaced without discarding the entire cutter body, keeping consumable costs low across high-volume CNC routing production.
- The 3-37/64 in. cutting diameter provides a wide kerf footprint, making this tool well-suited for large chamfers, deep V-grooves, and bold signmaking lettering in a single pass.
- With compatibility across chipboard, plywood, MDF, laminates, solid hardwood, and softwood, this cutter eliminates the need for material-specific tooling changes, streamlining workflow across mixed-panel production environments.

Frequently Asked Questions
What materials can this V-groove CNC bit cut?
The 663.130.11 is designed for general-purpose use on chipboard and plywood with its standard HWM reversible knife. A higher-quality knife grade is available for cutting laminated panels and MDF, making the cutter body adaptable across a broad range of sheet goods and solid wood materials.
Can the insert knives be replaced, and how does that benefit long-term use?
Yes - the HWM knives are reversible and replaceable. When one edge dulls, you can flip the knife to expose a fresh cutting edge, and when both edges are spent, only the knife needs replacing rather than the entire cutter body. This design significantly reduces long-term tooling costs for shops running high CNC production volumes.
What shank size is required for this bit, and which machines is it compatible with?
This bit uses a 20mm shank diameter and is intended for use with CNC router machines equipped with a matching collet or chuck. Its right-hand (RH) rotation is consistent with the spindle direction of standard CNC routers.
What is the cutting angle on this bit, and what does that mean for miter folding applications?
The cutting angle is 130 deg. This wide included angle is specifically suited for scoring panels so they can be folded into a 90 deg. miter joint - a common technique in cabinet carcass construction, point-of-purchase display fabrication, and channel letter signmaking. The 130 deg. geometry removes exactly the right amount of material so the remaining panel walls meet flush when folded.
