About this series
Solid Carbide Slitting Saws
Tight widths and finishes HSS can't hold.
RobbJack solid carbide slitting saws are ground to ANY thickness up to 0.250" in 0.0001" increments — the listing shows common price-break thicknesses, but every size in between is standard. Coarse-pitch teeth suit non-ferrous materials and fine-pitch suit ferrous; standard-concavity covers general use, while K-series double-concavity, alternate-tooth-chamfer versions handle deep cuts.
- Any thickness up to 0.250" in 0.0001" increments — every size between the listed price breaks is standard
- Minimum thickness by diameter: 0.002" (3/4"–1"), 0.004" (1¼"–2"), 0.006" (2¼"–4"); K-series 0.020"
- Coarse pitch for non-ferrous, fine pitch for ferrous
- Standard and K-series double-concavity / alternate-tooth-chamfer versions
- Optional T-Process, hub, keyway and PVD coatings
- Thru-coolant saw systems available on NAB / AB arbors with CF flanges
Mounts on AB and NAB saw arbors. Choose K-series double-concavity saws for slots deeper than 3× the saw thickness.

Thru-Coolant NAB Precision Saw Arbor
Slitting saws fail when coolant can't reach the cut — external flood gets blocked by fixturing and part geometry. The NAB arbor delivers coolant through the center and out through thru-coolant flanges onto both faces of every saw— equal pressure, right where the cut happens. Precision-ground to 25 millionths and grips the saw up to 15× more tightly — so it can't slip or spin on the arbor — for faster speeds & feeds, no walking, and far longer tool life.
- 0.000025″
- tolerance — 25 millionths
- 15×
- grip on the saw vs. a typical arbor
- ≈80%
- fewer causes of saw failure
- ↑ S&F
- faster speeds & feeds, longer life
Recommended for your 0.1968″ bore saw
Contact application engineering for the thru-coolant arbor that fits this saw bore.
Thru-coolant flanges are required. Add thru-coolant spacers to gang multiple saws. Solid carbide flanges last a lifetime and eliminate the burrs & scratches of steel.
Available in any thickness — 0.002″ to 0.2362″
This saw is stocked in 15 standard thicknesses, but any thickness between 0.002″ and 0.2362″ is a standard order, not a special — you order in ten-thousandths of an inch and RobbJack grinds it, priced as the next thicker catalog size. Thickness is held to +.0002″/−.0000″, and the part number carries your exact thickness. Enter your size in the in-between thickness panel above to get the part number and price. Saws thinner than .010″ are specials and non-returnable; most thicknesses from .008″ to .250″ ship within about 48 hours.
