Drills
1 mm Coolant-Through Drill: Micro-Bore Engineering at the Limit
At 1 mm diameter, routing high-pressure coolant through the tool body pushes carbide grinding, straightness, and sealing to the physical limit — a capability only a handful of factories worldwide can ship repeatably.

Drills
400 mm Overall Length: Coolant-Through Solid Carbide Drills
Delivering a straight, sealed coolant channel down a 400 mm solid carbide body pushes grinding, gun-drilling, and inspection to the limit — a specification only a small number of global plants can execute in volume without runout or leakage failures.

22 mm Diameter Solid Carbide Drills: High-Precision at Large Scale
Large-diameter drilling amplifies runout, thermal drift, and entry/exit shock. This 22 mm solid carbide drill case shows how we keep geometry stable to deliver accurate hole results despite the higher cutting forces of big diameters.

Drills
Double-Margin Coolant-Through Drills with TiSiN Coating
A double-margin lip layout guides the drill in the hole, supports the cutting edge under load, and pairs with through-tool coolant and TiSiN for cooler cuts and more predictable hole quality than single-margin designs in demanding materials.

Workshop Snapshot: Micro-Diameter, Deep Coolant-Through Drills (Before Coating)
This photograph was taken inside our Changzhou plant: micro-diameter bodies with very long flute length for deep-hole work, coolant-through construction, shown before coating — a class of tool that exposes every weakness in blank quality, bore straightness, and flute grinding.

Drills
Straight Flute Stepped Solid Carbide Drills: Multiple Diameters in One Setup
A stepped geometry drill reduces re-positioning and tool changes by machining multiple diameter holes in one setup. Straight flutes support efficient chip evacuation and stable cutting for repeatable step-to-step accuracy.

Workshop Photo: Flat Bottom Stepped Coolant-Through Carbide Drills (Before Coating)
Flat-bottom hole features demand stable guidance and a controlled cutting zone so the bottom stays truly flat and each step remains consistent. This workshop photo shows our stepped geometry with coolant inside before any coating is applied.

Drills
High-Performance Three-Point Flat Bottom Carbide Drills
A three-point flat bottom drill with self-centering brad point and outer spurs for clean, burr-free hole entrances. 180-degree flat bottom geometry delivers a nearly perfect flat base for blind holes and counterboring.

20 mm Forming Drills: Precision Built for Production Efficiency
A 20 mm forming drill is engineered to enlarge and shape holes with controlled geometry. The forming profile improves accuracy and repeatability while reducing secondary operations in production.

End Mills
ZrN Solid Carbide End Mills: High-Speed Slotting & Profiling
Zirconium nitride (ZrN) on a precision-ground solid carbide body lets shops push surface speed in aluminum and non-ferrous alloys while controlling built-up edge — ideal for high-speed slotting, profiling, and finishing passes where thermal stability drives tool life.

End Mills
Mould Industry: Custom Carbide Ball End Mills for Precision & Life
Mould shops need ball end mills that hold true radius and surface finish in 3D cavities, resist chipping in hardened P20 or H13, and survive long finishing programmes — this custom line targets precision, strength, and metre-after-metre life.

End Mills
Graphite Machining: Diamond-Coated Solid Carbide End Mills
Graphite is aggressively abrasive: standard carbide wears quickly and changes part geometry. A diamond-family coating on a precision-ground solid carbide body cuts wear rates dramatically so shops finish electrodes and graphite structural parts with fewer tool changes and more predictable dimensions.

End Mills
Custom 3-Flute Roughing End Mills (Before Coating)
Three-flute roughing end mills balance chip volume and stability for aggressive slotting and adaptive roughing. This batch was photographed in our workshop after grinding, before coating — the stage where profile, flute shape, and edge condition are fully defined for your custom programme.

Special Cutters
T-Slot & Keyseat Cutters: Solid Carbide Special Form End Mills
T-slots and keyseats need a true profile tool: a square or ball end mill cannot generate the undercut geometry in one pass. These solid carbide special cutters are ground for accurate width, depth, and corner radii where fixture access and tool strength both matter.

Special Cutters
Workshop: Coolant-Through T-Slot & Keyseat Cutters Before Coating
These custom profile cutters include through-shank coolant delivery to the cutting zone — a valuable option in deep or full-width T-slot passes. The photograph was taken on our shop floor after precision grinding and inspection, immediately before coating.

Special Cutters
Specialized Custom Forming Carbide End Mills
When the feature is not a square shoulder or a ball sweep — undercuts, compound radii, seal grooves, or blended walls — a forming end mill is ground to match the part profile. This case highlights how we develop custom carbide form tools for special machining programmes.

Special Cutters
Stepped Forming End Mills: Custom Profile for Production Accuracy
A stepped forming end mill is engineered when a feature cannot be finished accurately with square shoulders or ball sweeps. The stepped profile controls geometry in one tool pass, reducing operations and improving repeatability.

Christmas Tree Milling Cutter: Solid Carbide Profile End Mill for Fir-Tree Slots
Christmas tree cutters are designed for precise, multi-step fir-tree slot machining. The stepped, tapered profile supports symmetry in single-pass production, with grinding and inspection aimed at sub-micron class accuracy for critical turbine joints.

Reamers
Necked Solid Carbide Reamers: H7 & Ra 1.6 µm Performance
Custom necked solid carbide reamers ground for deep or obstructed bores — shown before PVD. Customer programmes target ISO H7 and Ra 1.6 µm hole quality with tool life in the same class as leading German reamer lines.
