Tungsten Carbide End Milling Cutter for CNC Steel Groove Cutting and Dimensional Finishing
A carbide end mill for steel groove cutting where the finished width and depth must hold size.
Design and Construction — a VPOINT solid tungsten carbide end mill for steel slotting, profiling and groove milling. The specification and performance tables below list dims, duty and inspection points; the FAQ covers selection, use and service. ISO 9001 production, batch-verified, custom sizes from drawings.
Design and Construction
A tungsten carbide end milling cutter for CNC steel work that combines groove cutting with dimensional finishing. Flute count is selected to leave enough chip space in a deep groove while keeping the core thick enough to resist deflection.
How It Works
Groove width is set by the tool diameter plus the runout; groove depth is limited by how well chips escape. A lower flute count clears chips in deep grooves, while a higher flute count gives more cutting edges for shallow finishing passes.
Applications
CNC keyways, locating grooves, sealing grooves, dimension-critical steel features.
Field Cases
- Machine shop: keyway width held across 60 parts without a tool offset change.
- Fixture maker: locating grooves finished to nominal width in one pass.
- Repair work: worn sealing grooves re-cut to the original dimension.
Performance Data
| Metric | Value / Observation |
|---|---|
| Primary duty | Groove cutting + dimensional finishing |
| Material | Tungsten carbide |
| Size control | Diameter + runout |
| Chip space | Flute count matched to groove depth |
Suitable Materials
Carbon steel, alloy steel and cast iron; stainless with reduced speed and adequate coolant.
Standard reference values for guidance only — always adjust to the workpiece material, the machine spindle speed and the feed, and confirm on the actual part.
Material Comparison: 2-Flute vs 3-Flute vs 4-Flute in Groove Work
Flute count changes chip space and core rigidity. Typical industry practice:
| Factor | 2 Flutes | 3 Flutes | 4 Flutes |
|---|---|---|---|
| Chip space | Largest | Moderate | Smallest |
| Core rigidity | Lowest | Moderate | Highest |
| Deep groove capability | Best | Good | Limited |
| Feed rate at a given chip load | Lowest | Medium | Highest |
| Finishing surface | Adequate | Good | Best |
| Typical choice | Deep slots, aluminium | General steel work | Shallow grooves, finishing |
Delivery Scope
Single end mill; flute count and diameter confirmed with the order.
Why Choose VPOINT
Groove dimensions are a function of tool diameter and runout – both are controlled and stated.
Precision & Quality Control
Cutting diameter, flute symmetry and shank runout checked per lot with full batch traceability.

Frequently Asked Questions
Which flute count should I choose?
More flutes give a better finish and higher feed; fewer flutes clear chips in deep grooves.
What sets groove width?
Tool diameter plus runout – both are controlled per lot.
Can it hold size across a batch?
Yes, the solid carbide edge holds diameter through repeated groove cuts.
Is stainless suitable?
Yes, with reduced speed and adequate coolant.
How deep can the groove be?
Depth is limited by chip evacuation; use air or coolant and reduce feed as depth grows.
