Why Choose Our T-Slot Milling Cutters
Solid Tungsten Carbide
Sub-micron grain carbide with TiAlN coating — cuts 3× longer than HSS equivalents at the same Vc, with sharper T-slot profile walls and longer edge retention.
DIN 850 / ISO 3337 Profile
T-slot sidewall angle and bottom radius follow DIN 850 / ISO 3337 standard — drop-in compatible with T8-T36 machine-tool table slots.
5 Tooth Lengths per SKU
Every diameter ships in ×1 / ×1.5 / ×2 / ×2.5 / ×3 tooth-length variants — match slot depth without buying separate cutters.
Sharp Sidewall Finish
Ground peripheral teeth and bottom geometry leave a clean slot wall — minimal deburring, no secondary hand-deburring pass on the T-slot shoulder.
T-Slot Profile Standards (DIN 850)
The T-slot profile on your workpiece must match a standardized dimension for the cutter to seat correctly. DIN 850 defines the most common T-slot table dimensions used on milling-machine beds, fixture plates, and clamping elements. Our cutters are ground to match the slot width (T-slot nominal) and produce the sidewall angle and bottom relief per ISO 3337.
| T-Slot Nominal (a × b) | Cutter D1 (mm) | Bolt Size | Typical Workpiece |
|---|---|---|---|
| T8 (8 × 15) | 8 | M6 | Small fixturing, gauge blocks |
| T10 (10 × 18) | 10 | M8 | Standard milling-machine tables |
| T12 (12 × 22) | 12 | M10 | Medium-duty machine beds |
| T14 (14 × 25) | 14 | M12 | Fixture plates, clamping rails |
| T16 (16 × 28) | 16 | M14 | Large machine-tool tables |
| T18 (18 × 32) | 18* | M16 | Heavy-duty fixturing |
| T20 (20 × 36) | 20 | M18 | Industrial machine beds |
| T22 (22 × 40) | 22* | M20 | Large press beds |
| T24 (24 × 45) | 24* | M22 | Custom heavy machinery |
| T28 (28 × 50) | 28* | M24 | Extra-large fixturing |
| T36 (36 × 60) | 36* | M30 | Press-tool bases |
* Diameters 18 / 22 / 24 / 28 / 36 mm available on request — our stocked range is 2-20 mm. For T-slot cutters in aluminum-specific geometries, see our aluminum T-slot milling cutter collection.
Size Selection Guide (2-20mm)
All standard sizes ship within 24 hours from our Hangzhou warehouse. Pick by cutter diameter (D1) — that value equals the T-slot nominal width your slot must match. View any individual size below:
| Cutter D1 | Typical T-Slot | Common Workpiece | View |
|---|---|---|---|
| 2 mm | Specialty / micro-fixturing | Jewellery fixtures, watch tooling | 2mm version |
| 3 mm | Micro fixture slots | Small clamps, precision tooling | 3mm version |
| 4 mm | Light fixturing | Electronics fixtures, PCB tooling | 4mm version |

| 11 mm | Mid-heavy clamping | Heavy fixture plates | 11mm version |
| 12 mm | T12 standard | Medium-duty machine beds | 12mm version |
| 14 mm | T14 standard | Clamping rails, fixture plates | 14mm version |
| 16 mm | T16 standard | Large machine-tool tables | 16mm version |
| 20 mm | T20 standard | Industrial machine beds | 20mm version |
5 Tooth Length Variants per Diameter
Every diameter ships in 5 tooth-length variants — measured as the cutter's cutting-depth ratio relative to D1. Pick the variant that gives at least 1 mm of cutter clearance past the bottom of your T-slot. All 5 variants are priced the same per SKU, so you can hold one of each in your drawer and stop swapping cutters between jobs.
| Variant | Cutting Depth | Use When |
|---|---|---|
| ×1 | 1.0 × D1 | Standard slot — matches most T-slot profile depths. |
| ×1.5 | 1.5 × D1 | Deeper T-slots where standard ×1 is too shallow. |
| ×2 | 2.0 × D1 | Deep slots, extended fixture channels. |
| ×2.5 | 2.5 × D1 | Heavy-duty slotting, large fixture plates. |
| ×3 | 3.0 × D1 | Maximum depth for oversized T-slot profiles. |
Recommended Cutting Parameters
Starting parameters for solid-carbide T-slot cutters in TiAlN-coated grade. Adjust Vc down 20% for stainless steel or interrupted cuts. Use coolant (flood or MQL) for any cut deeper than 1 × D1.
| Workpiece Material | Vc (m/min) | fz per tooth (mm) | ap (pass depth) | Coolant |
|---|---|---|---|---|
| Mild Steel (S235 / 1018) | 80 - 120 | 0.03 - 0.06 | 0.5 × D1 | Flood or MQL |
| Alloy Steel (4140 / 42CrMo) | 60 - 90 | 0.025 - 0.05 | 0.4 × D1 | Flood |
| Stainless Steel (304 / 316) | 40 - 70 | 0.02 - 0.04 | 0.3 × D1 | Flood (mandatory) |
| Cast Iron (GG25 / GGG40) | 70 - 100 | 0.04 - 0.08 | 0.5 × D1 | Dry or MQL |
| Aluminum (6061 / 7075) | 150 - 250 | 0.05 - 0.10 | 1.0 × D1 | MQL or flood |

T-Slot Cutter vs Side Mill vs End Mill
Each tool is engineered for a different slot geometry. Choosing the wrong one wastes time on secondary hand-deburring or produces a slot that doesn't seat standard T-nuts. Here's when to reach for which:
| Operation | Reach For | Why |
|---|---|---|
| Standard T-slot profile (DIN 850) | T-slot cutter | Ground to match T-slot nominal width + sidewall angle in a single pass. |
| Open-ended slot (no closure) | Side mill or end mill | Open slot allows chip evacuation without T-slot profile. |
| Closed slot / keyway | End mill + keyway cutter | Slot must be plunge-cut, then opened with side mill. |
| Profile sidewall (free-form) | End mill or profile mill | 2D or 3D contour with full cutter engagement. |
| Heavy stock removal in slot | Face mill + side mill | Faster MRR for rough opening before T-slot profile pass. |
Browse corn-milling cutters for profile work, face-milling cutter series for surface facing, or chamfering cutters for edge-breaking after T-slot cutting.

Frequently Asked Questions
What T-slot standard do these cutters conform to?
All cutters in this range are ground to DIN 850 T-slot profile geometry, cross-referenced with ISO 3337. The cutter diameter (D1) equals the T-slot nominal width (e.g. 10 mm cutter → T10 slot). The sidewall angle and bottom relief match standard machine-tool table slots used on most milling machines.
What carbide grade is used, and is it coated?
Sub-micron grain tungsten carbide (K20-K30 equivalent ISO classification) with a TiAlN (Titanium Aluminium Nitride) coating. TiAlN gives higher hot hardness than plain TiN, allowing higher Vc in steel and stainless steel without rapid edge wear. The coating also reduces built-up edge when cutting aluminum.
Do I need coolant, or can I run these dry?
For steel / stainless steel: flood coolant is mandatory for any cut deeper than 1 × D1, especially the ×2 / ×2.5 / ×3 variants. For cast iron: dry or MQL is fine. For aluminum: MQL or flood both work — MQL gives the best chip evacuation. Without coolant, expect accelerated wear on the sidewall teeth and potential chip welding on the T-slot bottom radius.
📦 Shipping cost & delivery time for individual buyers?
We ship to 50+ countries via DHL / UPS / FedEx. Most orders deliver in 3-7 business days. Shipping cost is calculated at checkout based on destination — typically $15-$35 for a single T-slot cutter to North America / Europe / Asia-Pacific. Tracking link is emailed within 24 hours of dispatch. We also ship to home addresses (not just commercial).
🛒 Can I order just 1 piece to try?
Yes — 1 piece welcome. No MOQ, no bulk-buy requirement. Single-piece orders get the same DHL/UPS/FedEx tracked shipping as bulk orders. Volume discount is automatic in cart: 2-9 pieces 6% OFF, 10+ pieces 12% OFF — but you never have to hit those tiers to place an order.
⇆ Returns & warranty?
30-day return window for unused product in original packaging. If a cutter arrives damaged or defective, we ship a replacement free of charge (you keep the original). For production-line failures (edge chipping under normal use within the first 10 cuts), send a photo to chao@cnchome-beyond.com or WhatsApp +86 15990663752 and we’ll troubleshoot or replace.
