Serrated blade milling cutters with replaceable blades
Blade milling cutters with replaceable serrated blades — six families for slotting, shouldering and face milling in the UK.
Galtona's Serrated Blade Cutters use a forged and heat-treated alloy steel body carrying replaceable serrated High Speed Steel (or cemented-carbide-tipped) blades — resizable with minimal regrinding by reinserting each blade one slot ahead, which moves the cutting edge out a few thousandths of an inch.
No. 600 Alternate Angle cutters (Ø4"–16") stagger blades for keyway and slotting work. No. 610 Interlocking pairs join two No. 620 Half Side cutters for wide slotting and channeling. No. 630 Straight Blade cutters suit general-purpose milling.
The same blade system is also offered as shank-type (640/640X), arbor-type (650/650X), centring-arbor (660C/660CX), and BS 122-1953 (B650/B650X) shell and face mills, in light, medium, and heavy-duty variants.
No. 900/920 cutters use the same alternate-angle and interlocking designs but with cemented-carbide-tipped blades, in cast-iron (G) and light-alloy (M) grades, for high-production slotting.

Shell & Face Mills — Shank, Arbor & Centring Mount
HSS, Nos. 640/640X, 650/650X, 660C/660CX, B650/B650X — light, medium, and heavy-duty mounting styles.
Galtona shell and face mills use the same Serrated Cutter Blade system in four mounting styles, made to suit varying duty — light, medium, or heavy:
- No. 640 / 640X — shank type, for milling small faces, steps, or channels. Standard (640) or heavy-roughing (640X) blade sets.
- No. 650 / 650X — arbor type shell end mills, adaptable to any milling machine or horizontal boring mill via a separate arbor.
- No. 660C / 660CX — centring arbor type; cutter is driven direct by keys in the milling-machine spindle, with the arbor only centring and holding it against the spindle nose — a heavy-duty drive for small face mills.
- B650 / B650X — small face mills built to fit British Standard BS 122-1953 arbors, for shops converting from solid HSS face mills.
