This 55HRC 4 flute t slot end mill is engineered specifically for high-efficiency aluminum machining. With a reinforced neck and precision-ground undercut, this t slot mill cutter finishes the complete T-profile in one t slot cutting on milling machine operation, reducing tool changes and improving slot consistency.
Made from fine-grain carbide, this carbide t slot milling cutter combines high hardness with excellent toughness for stable high-speed t slot milling in aluminum and non-ferrous alloys. Polished flutes and optimized chip space help avoid built-up edge and ensure smooth chip evacuation during continuous t slot milling operation.
Grade HN40 is made from submicron WC powder, some speclal additlves added to optimize theproperties with good combination of hardness and toughness.
Its suitable for making drills and miling tools for machining stainless steel, tool steel and heat-resistingalloys.

| Bright | Nano-polishing layer: ultra-smooth surface formed by PVD or CVD, optionally with added Si or B elements. Metallic gloss layer: may contain highly reflective TiN (titanium nitride) or CrN (chromium nitride), giving a bright silver or golden appearance. | Hardness: 2500–3500 HV (nano-indentation). Friction coefficient: 0.1–0.2 (down to 0.05 for DLC composite coatings). Heat resistance: 600–800 °C (DLC may oxidise above 400 °C). Adhesion strength: ≥50 N (scratch test). Surface roughness: Ra < 0.02 µm (after polishing). | Mirror finish: nano-scale multilayer structure reduces surface defects and minimises the need for secondary polishing of the workpiece. Anti-adhesion: oleophobic / hydrophobic design (e.g. fluorine-containing compounds) prevents sticking of soft materials such as aluminium and copper. | Recommended materials: non-ferrous metals (aluminium, copper, magnesium alloys), high-finish steels (mould steels such as P20, NAK80; stainless steels 304, 316), composites (CFRP) and engineering plastics (PEEK, PTFE). Typical applications: precision moulds (mobile-phone housings, optical lens mould inserts), medical devices (artificial joints, dental implants), electronic components (aluminium heat sinks, copper electrodes). |
A t slot end mill is a special t slot milling cutter designed to machine the undercut of a T-shaped groove in one pass. It is used in t slot milling operations on machine tables, fixtures and mold bases where standard end mills cannot reach the undercut area.
A standard end mill can rough the straight portion of a slot but cannot form the undercut. A t-slot end mill cutter or t-slot cutter milling tool has a special head that cuts both flanks of the T-shaped groove, completing the profile in one t slot cutting on milling machine step and ensuring consistent slot geometry.
An indexable t slot milling cutter or t-slot milling cutter insert type is ideal for high-volume production, larger slot sizes and harder materials where insert changes are more economical than replacing an entire solid t slot end mill. It also allows you to use different insert grades for steel, stainless steel or cast iron.

HNCarbide t slot end mill tools are designed for reliable T-slot machining in machine tables, fixtures and mold bases. Whether you are producing new t slot milling table surfaces or refurbishing worn clamping slots, our t slot milling cutter range delivers stable performance on steel, stainless steel, aluminum and cast iron.
From standard workholding milling machine t slot cutters to special profiles and deep slots, these t-slot end mills support precise t slot cutting on milling machine centers and conventional mills. Combined with appropriate t slot milling operation strategies, they help you achieve accurate slot dimensions, smooth side walls and secure clamping surfaces in one efficient t slot milling process, reducing set-ups and rework across your production line.
Each HNCarbide t slot end mill is manufactured from fine-grain solid carbide and finished on advanced CNC grinders to ensure consistent slot width and undercut geometry. Optimized flute design and neck clearance give our carbide t slot milling cutter smooth chip evacuation and stable cutting, even in continuous t slot milling on tougher materials.
We offer a wide range of t slot milling cutter sizes and styles, including indexable t slot milling cutter and t slot milling cutter insert type options to reduce tool cost in high-volume jobs. Tight control of diameter, runout and tooth form means every t slot mill in the family matches your print and fixture requirements, making HNCarbide a dependable choice for t slot cutter in metalworking end mills applications.
