Key Features & Benefits
- 20 cutters covering 10 diameters — Two-flute and four-flute versions in 3, 4, 5, 6, 8, 10, 12, 14, 16 and 20mm — one box, almost every job covered.
- Two-flute for slotting and aluminium — Open flute design clears chips fast in soft materials and full-width slots.
- Four-flute for steel and finishing — More cutting edges per revolution gives better surface finish and higher feeds in steel.
- TiN coating — Lower friction and higher surface hardness than uncoated HSS — extends life and runs cooler.
- Weldon shank, DIN 844 standard — Locks positively in side-lock holders so the cutter can’t pull out under heavy axial load.
When to Use This Tool
H-522-51-2S1 is the foundation tooling kit for any small workshop, training school or home machinist setting up a manual or benchtop CNC mill. The Weldon shanks suit traditional side-lock holders, and the TiN coating gives meaningful life over plain HSS.
Pro Tip: Use the four-flute cutters for finishing passes on steel and reach for the matching two-flute when you need to plunge or slot in aluminium — the wider flute on a two-flute keeps gummy aluminium chips from welding to the cutter.
