Proven in the cut · Tungaloy NTK

The latest tool tech, proven in the cut

When our application specialists are on your floor, this is what they're reaching for. The newest Tungaloy NTK technology — high-performance turning, high-feed milling, and drilling — applied to the materials and parts that decide whether a job runs profitably. (For aerospace heat-resistant alloys, see the ceramic and BIDEMICS lineup above.)

Featured · High-performance turning

AddMultiTurn: one tool, every direction

A single indexable tool turns front, back, profile, and face — no tool changes, no extra stations. New low-force chipbreakers and high-feed back-turning pull time out of the operation while keeping the edge in the cut longer, and six corners per insert keep cost-per-part honest.

Featured · High-feed milling

DoFeedTri: shallow cut, serious feed

High-feed milling takes a light axial depth and runs it at aggressive feed per tooth. The low lead angle drives cutting force up into the spindle, so the setup stays stable while metal comes off fast — built for roughing pockets, faces, and dies. DoFeedTri's double-sided inserts carry six cutting edges, so the speed doesn't come with a cost-per-edge penalty.

Tungaloy NTK · Drilling & chip control

Keep drilling. Change heads in seconds.

DrillMeister's self-locking carbide head swaps right on the machine — no pulling the body, no re-touching offsets — so you drill instead of regrind, holding solid-carbide hole tolerances from ø4–25.9 mm. Backed by Tungaloy NTK grades built for stainless and difficult-to-cut materials.

Tungaloy · Grooving & parting-off

AddForceCut: rigid where cutoff gets deep

Deep grooving and parting punish a weak insert seat — the edge deflects, chips pack the slot, and cutoff walks off size. AddForceCut locks a single-ended insert into a self-clamping seat with three contact faces and a stopper, so it holds position through deep, interrupted cuts and evacuates chips cleanly. A single-ended edge reaches deeper and parts larger bar — up to 120 mm (4.72″) — without a second edge fouling the workpiece.

Micro tooling · HB microtec

Small tools in hard material — the combination that kills everything else

A general-purpose end mill scaled down to 1 mm is still a general-purpose end mill. It does not survive cobalt-chrome. HB microtec builds the whole range the other way round: rotationally symmetrical tools from 0.1 to 8 mm, with substrate, geometry and coating matched to hard, heat-resistant and abrasive materials from the start. That is the entire business, not a corner of a catalogue.

ACTIONMILL® & TARGETMILL®

Built for the materials that decide the job

Cobalt-chrome, nickel and titanium alloys — the materials behind medical implants, aerospace structure and mould work. HPC, HSC, plunge, ramp and trochoidal milling, plus 3D profiling, roughing and finishing. The INOX-CORD, HPC, Finish and Trochoid mills all run internal coolant, which is what keeps a small tool alive in titanium.

ACTIONMILL® INOX Groover

One cutter does the roughing and the finishing

Ramp to 70°, cut a full groove, and plunge vertically at 90° like a drill — with the same tool, at high cutting values and depths. The saving is not the tool cost. It is the tool changes, the extra pocket in the carousel, and the setup sheet that no longer needs two lines where it used to need one each way.

ACTIONDRILL® & TARGETDRILL®

Holes small enough that the drill is the hard part

Centering, chamfering, drilling, reaming and countersinking from 0.1 mm up, with through-tool coolant on the deep-hole range. Below about a millimetre the drill stops being a consumable and starts being the process — runout, chip evacuation and coating decide whether the hole is round and whether the tool survives the second one.

ACTIONMILL® Lollipop · 305° & thread milling

Finish it on the machine, not at a bench

Three-flute 305° ball end mills from 0.8 to 10 mm on a long, stable neck reach front and rear burrs, internal and external contours, bore intersections and angled hole exits in the same setup. T-Slot cutters and custom-ground deburring forms round out the range, with diameter, length, shape and flute count matched to the part.

Torx® profiles · ISO 10664

The screw profile nobody wanted to quote

Surgical and dental screws use a six-lobe star socket because it carries far more torque than a hex of the same diameter — which matters when the screw is 1.5 mm across and the surgeon only gets one attempt. Cutting that profile small has always been slow and expensive. HB microtec builds dedicated tooling for it, so the socket comes from one operation instead of a broach, a second setup and a scrap rate.

New for 2026 · TARGETDRILL thread-drill-mill

Drill it, thread it, chamfer it — without changing tools

Three operations normally means three tools, three changes and three chances to be out of position. The TARGETDRILL thread-drill-mill drills the core hole with its point, mills the thread helically, and chamfers the lead-in with its step shoulder — in one sequence. The point also cuts an extended thread undercut at the bottom of the hole, which is usually a fourth operation.
