Solid Carbide End Milling Tool for Steel Slot Production and Contour Finishing
A solid carbide mill set up for both full-width slotting and contour finishing on steel components.
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 solid carbide end mill specified for steel slot production and contour finishing. The flute geometry balances chip evacuation in a full-width slot against the fine chip load needed for a clean contour pass, so one tool can rough a slot and finish the wall.
How It Works
In slotting, chips must clear a channel that is as wide as the cutter; in contour finishing, only a thin radial engagement is taken. The tool uses constant feed per tooth with the chip load adjusted for each operation rather than one fixed setting.
Applications
Steel plate slotting, bracket contouring, pocket walls, general CNC jobbing in carbon steel.
Field Cases
- Fabrication shop: full-width key slots and the surrounding contour were completed with one tool setup.
- Bracket production: contour passes removed the witness line left by roughing without a second tool.
- Maintenance CNC: worn fixture locating slots re-cut to a clean nominal width.
Performance Data
| Metric | Value / Observation |
|---|---|
| Operations | Full-width slot + contour finish |
| Construction | Solid carbide |
| Primary workpiece | Carbon and alloy steel |
| Setup | Single tool for rough and finish |
Suitable Materials
Carbon steel, alloy steel, cast iron; suitable for 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: Slotting vs Contouring vs Side Milling with One Tool
How the same cutter behaves under three engagement patterns. Typical industry practice:
| Factor | Full-Width Slot | Contour Finish | Side Milling |
|---|---|---|---|
| Radial engagement | Full cutter width | Light (5-15% of D) | Moderate (20-40% of D) |
| Chip evacuation | Most demanding | Easy | Moderate |
| Feed per tooth | Reduced | Increased slightly | Nominal |
| Heat in the cut | Highest | Lowest | Moderate |
| Surface on the wall | Roughing marks | Finishing pass | Semi-finish |
| Tool change | None if one tool | None if one tool | Often a second tool |
Delivery Scope
Single end mill; flute count and diameter confirmed with the order.
Why Choose VPOINT
One tool covering two operations reduces tool changes on small batch steel work.
Precision & Quality Control
Flute symmetry, edge preparation and shank runout inspected per lot under ISO 9001 batch records.

Frequently Asked Questions
Can one tool really rough a slot and finish a contour?
Yes – adjust chip load and radial engagement between the two operations rather than holding one fixed feed.
What is the main risk in full-width slotting?
Chip evacuation. Reduce feed per tooth and use air or coolant to clear the channel.
Which steels?
Carbon and alloy steels primarily; stainless is possible at reduced speed.
Will the contour pass leave a visible line?
A light finishing pass with a sharp tool removes the witness line left by roughing.
Is runout checked?
Yes, shank runout and flute symmetry are verified per lot.
