No. 630 — Straight Blade Milling Cutters
No. 630 — Straight Blade Milling Cutters
HSS, general-purpose, blades set straight for both sides of the tooth. Diameters 4"–16".
For general purpose use. Cutter blades set straight allow both sides of the tooth to come into the work at once, neutralising side cutting thrusts — spiral-angle cutters (No. 600) are recommended wherever possible instead.
