20mm Dia. 5mm Arbor 10 Teeth Alternate Tooth Chamfer Carbide Saw Non-Ferrous
20mm Diam. Slitting Saw, 2mm Thick, 5mm ID, 10 teeth Alternate Tooth Chamfer, Double Concavity, 12mm Hub
K-Series double-concavity. Built for deep slotting — these alternate-tooth-chamfer saws cut cleaner and last longer than standard saws in slots deeper than 3× the saw thickness.
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 — 0.0236″ to 0.2362″
This saw is stocked in 10 standard thicknesses, but any thickness between 0.0236″ 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.
