Rough-Duty Single-Sided Ball Nose Inserts – RDBN Series

RDBN is a stronger insert for our standard Ball Nose end mill line, designed to stand up to more demanding light roughing and finishing applications: heavier cuts, long tool overhangs, and tougher materials.

Click here for demo footage of these inserts in action as we heavy 3D rough 1018 steel, semi-finish hardened H13 (50 Rc), and corner round 1018 low-carbon steel.

Tougher carbide substrate for added shock resistance
Stronger ground cutting edges for extra strength and durability
Helical geometry for reduced cutting forces
Fit all standard Dapra Ball Nose end mill cutter bodies (not EDGE² SBN series)
Available in our new TS and HM coatings
