ASM2 – 3-Flute Arc Tenon Router Bit for Round Tables

The ASM2 is a 3-flute arc tenon router bit listed for round-table mortise arc cutting. It has a 12.7 mm (1/2 inch) shank, a 50 mm cutting width and an R4 curvature. Use the arc dimensions in the joint drawing and a test piece to confirm the resulting fit.

Listed specifications

Match the bit to the joint

• Check that the 12.7 mm shank matches the router collet, CNC spindle or holder.
• Compare the R4 curvature and 50 mm cutting width with the arc or tenon geometry in the project drawing.
• Confirm the cutting depth, workpiece thickness and machine clearance before setting the tool height.
• Plan secure workholding for the curved or round-table component so it cannot move during the cut.

Test cut and safe use

Make a test cut in matching scrap and check the arc, depth and joint fit before machining the finished component. Use the machine maker’s speed, feed, guarding and cutter-installation instructions. Stop if the tool chatters, overheats or shows damage, and inspect the cutting edges before reuse.
