Bull Nose and Ball Nose Corner Radius Attachment, CM-03D

The most versatile attachment for your CUTTERMASTER tool grinder (or any similar tool grinder) is Made-in-North America and adds several secondary tool grinding operations to your shop

• Corner radius on end mills (bull nose and ball nose)
• Easy center cutting end mill ends
• Neck relief / diameter reduction
• Tool cut off
• Weldon set screw flats

Precision machining and hand-built attention to detail make bull nose and ball nose corner rads fun, when added to your tool grinder.

In addition to the CM-03D Radius Attachment, to grind corner rads, you’ll need a wheel with a sharp corner that is trued and dressed, as well as a couple of other things to make the job easier. Here is a list describing a recommended complete set up for corner rads.

• Cuttermaster Traditional Tool Grinder – or similar tool grinder
• CM-PS1 Tool Grinder Wheel Kit – 11V9 resin bond cup wheels and wheel truing device
• Magnetic Dial Indicator or Digital Read Out
• Machinist’s square

Center cutting ends can be achieved easily using the CM-03D. The set up (plunging center cutting ends with a plated rim wheel) shown here uses Cuttermasters’ Easy Ends kit which is a plated rim wheel with spindle extension and a dial indicator to keep track of table movements.

For center cutting ends, add to your kit

• CBN or diamond plated rim wheel
• 2-1/2″ spindle extension
• Magnetic Dial Indicator or Digital Read Out

Add one of our plated neck grinding wheels for tool diameter reduction (chamfer wheel for Weldon set screw flats shown, also works).  Also needed is the 2-1/2″ spindle extension.

• Diamond neck wheel
• Diamond neck wheel for small tools
• CBN wheel for HSS (making T cutters)

Add one of our plated chamfer wheels for Weldon set screw flats.  Also needed is the 2-1/2″ spindle extension.

• Diamond chamfer wheel for carbide

Cut off carbide by adding a diamond cut off wheel. Also needed is the 2-1/2″ spindle extension.
