When the catalog doesn't have it, we engineer it.
A catalog ends where your part begins. NSIT engineers and sources the special and custom tooling that catalog houses send back — from a modified standard to a full made-to-print tool — with one goal: cutting your cost per part, cycle time, setup, and tool changes. Backed by our application specialists and premier partners like ARCH Cutting Tools and AB Tools.
Made-to-print customs
Bring a print; we engineer the special through our partners — ARCH Cutting Tools, AB Tools, Mikron Tool and more — and prove it on your machine. Step drills, custom form tools, complex multi-feature round tools, special diameters, PCD and CBN — combined to take steps out of your process.
Modified & custom-ground standards
Often you don't need a clean-sheet special — just a standard tuned to your job: altered diameters, corner radii, necks, reach, and coatings. Faster and lower-cost than a full custom, ground to your feature.
Custom NSHP end mills
Our private-label NSHP line goes beyond the 292 stock SKUs — custom solid-carbide end mills to your diameter, flute count, geometry, and coating. Engineered in the USA, precision-crafted in Poland, at NSHP pricing.
Used tooling → usable again
Don’t buy new steel to get a special. Worn inserts and round tools can be reground to spec — or downsized into a smaller standard size or a different form. Regrinds run about half the price of a new insert, in carbide, ceramic, cermet, PCD and CBN, held to new-tool tolerances. Ship us the used tooling; we sort it, quote what’s serviceable, and credit the rest.

Line down? Quote in 4 hours. Tool in 5 days.
When a tool breaks and the job is on the clock, lead time is the problem. Through ARCH’s HOTSHOP! program we expedite most solid carbide round tools — quoted in four hours, manufactured and shipped in five days or less (ten for large quantities) — including custom features for chamfering, pre-drill prep, finishing, and corner contouring.
Does my tool qualify? — diameter & length limits
HOTSHOP! covers most solid carbide round tools within these maximum overall lengths. Outside the range? Send it anyway — we’ll quote it as a standard special.
