Design and Construction

The 90°/120° V-groove signmaking CNC router cutter pairs a 40Cr chrome-molybdenum steel body with replaceable tungsten carbide insert knives. Alloy steel body carrying insert knives; 90° and 120° included angles for sign work. The specifications table states application (soft and hardwoods, particle board, MDF), net weight and packaging, plus the product code and size list.

How It Works

The insert knives seat in precision pockets and present ground carbide edges to the workpiece. When an edge dulls, the knife is turned to its second edge or swapped in minutes — the body, its shank and its concentricity stay on the spindle, and the next cut lands at the same dimension.

Applications

90°/120° signmaking V cuts
Deep V-groove sign work
Display and sign production
CNC sign cutting

Suitable Materials

Melamine-faced particleboard
MDF and laminated boards
Plywood and veneered panels
Solid wood

Suitable materials: melamine-faced particleboard, MDF, laminate HPL, veneered plywood, solid hardwood

The insert knives hold the 90° and 120° V profiles through deep sign cuts.

System Comparison: Replaceable Insert vs. Solid Knife

Insert bits keep the steel body in service and replace only the cutting edges. For production routing and panel work, this is usually the lower-cost way to hold edge quality.

Property	Replaceable Insert Knife (This Tool)	Solid Profile Knife
Edge replacement	Swap the worn insert only; the steel body stays in service	Regrind or replace the complete tool
Body material	40Cr chrome-molybdenum steel body, reused across insert changes	Whole tool consumed as the edge wears
Downtime per edge change	Minutes — index or swap the insert	Send out for regrinding or buy a new tool
Profile changes	Fit a different insert geometry to the same body	New tool required per profile
Edge condition	Fresh edge on every change; consistent cut quality	Edge quality drifts between regrinds
Best suited for	Production cutterheads with repeat profiles	One-off profiles and low-volume work

Solid knives remain the better choice for one-off profiles and very low volumes.

Delivery Scope

Single bit. Order by product code with the diameter, shank, cutting length and tooth count stated in the specifications table below.

Why Choose VPOINT

One-year warranty on every cutter — defects in material or workmanship are covered for 12 months from delivery.
Custom tooling — diameters, bores, cutting widths and tooth counts built to your drawing or sample.
Non-standard fabrication — profiles and sizes outside the standard catalogue, including profile restoration.
Resharpening service — cutters return to service after regrinding at a fraction of new-tool cost.
Factory-direct since 2008 — ISO 9001 manufacturing in Sichuan and Dongguan, China; 40Cr chrome-molybdenum steel bodies; no trading intermediaries.

Send a drawing, a sample or a worn tool, and our engineering team will quote the exact specification you need.

Precision & Quality Control

Every cutter is inspected at micron level before shipment. Cutting diameter (ØD), bore (Ød), cutting width/height (B/H) and overall dimensions are measured against the values listed in the specifications table, and cutting edge runout and concentricity are verified on the assembled tool.

Tools measuring outside tolerance are reground or scrapped — they do not ship. Inspection is performed under our ISO 9001 quality system, with batch records retained for traceability.

Performance Data

Standard reference values for guidance only — always adjust to machine rigidity, clamping and tool wear, and confirm on the actual workpiece.

Material	Typical spindle speed	Typical feed	Notes
MDF	18,000–22,000 rpm	8–12 m/min	Insert knives hold diameter on abrasive MDF
melamine-faced board	18,000–22,000 rpm	6–10 m/min	Constant diameter keeps knife changes invisible
particleboard	18,000–22,000 rpm	8–12 m/min	Rotate the knife at the first sign of fuzzing
laminated panel	18,000–20,000 rpm	6–10 m/min	Finer grain carbide than brazing allows
plywood / veneered panels	18,000–22,000 rpm	8–12 m/min	Clean edges through alternating grain
