Indexable Sawing
Slitting saws, T-slot cutters, holders and inserts that all work together — pick your system, then match the parts.
Indexable sawing splits into two families. They don't mix — the holders, bodies and inserts are only interchangeable within a family. Start by picking the cut you need to make.
UFO Indexable T-Slot & Slitting
Small-diameter blades and cutters carried on a shank holder that goes straight into the spindle. For narrow slots, T-slots, undercuts and circlip grooves.
Indexable Slitting Saws
Large-diameter side milling cutters that mount on an adapter holder. For deep slots, parting off and side-and-face work on a machining centre.
System 1 · Shank-MountedUFO Indexable T-Slot & Slitting
UFO Solid Slitting Blades
A one-piece carbide disc — cutter and insert in one. Index it round, then replace.

UFO Toolholders
Shank holder that clamps the blade. Choose by blade diameter, overall length and neck diameter.

UFO T-Slot Cutter Bodies
3T bodies that take separate LNGT inserts — for wider slots and T-slot profiles.

Indexable Slitting Saw Inserts
LNGT inserts for the 3T cutter bodies — full radius and neutral, in four grades.

QuestionsIndexable sawing FAQs
What's the difference between an indexable slitting saw and an HSS one?
An HSS or carbide-tipped slitting saw is a single solid blade — when it's blunt you re-sharpen or replace the whole thing. An indexable saw has a steel body with replaceable carbide inserts, so you only replace the cutting edges. The body lasts for years, and you can change insert grade to suit the material without buying a new saw.
What is a UFO solid blade?
It's a one-piece carbide disc that acts as both the cutter and the insert. It clamps into a UFO toolholder and, because there's no body to fit inserts into, it can go much thinner and smaller than a conventional indexable saw — down to 1.5 mm wide and 12 mm diameter.
Which adapter holder do I need?
Match the spigot size on the adapter to the bore of the cutter body, and check the adapter covers your saw diameter. As a rule, Ø80–100 mm bodies take a 22 or 25.4 mm spigot and Ø125–160 mm bodies take 31.75 or 32 mm. Keep the overhang as short as your setup allows — a shorter reach gives a more rigid cut with less runout.
Can I use the same inserts in both systems?
Only where the insert code matches. The UFO 3T cutter bodies take LNGT; the large arbor-mounted bodies take SNGX/SNGW and CNGX inserts. Always order by the insert designation printed on the product, not by diameter.
How narrow a slot can I cut?
Down to 1.5 mm with the UFO solid blades. The arbor-mounted indexable saws start around 3 mm. Below 1.5 mm you're into solid HSS or carbide slitting saw territory — see the solid range above.
