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.
