The ACRT3 is a 5.7-degree tapered chamfer bit for controlled angled edge work in wood and panel projects. The 5.7-degree taper is the listed profile for this model; it should not be described as a 45-degree chamfer. Use a test piece to confirm the profile against the finished-part drawing.

Listed specifications

Choose the setup before ordering

• Match the 12.7 mm shank to the router collet, CNC spindle or holder.
• Check that the 50 mm cutting length and 90 mm overall length fit the machine guard, collet engagement and available clearance.
• Compare the 5.7-degree profile and listed bottom dimension with the edge or chamfer shown in your drawing.
• Confirm the workpiece thickness, workholding and cutter height before routing a finished part.

Test cut and safe use

Secure the stock and make a shallow test pass in matching scrap first. Check the angle, edge position and surface finish before moving to production material. Use the machine maker’s speed, feed, guarding and cutter-installation instructions, and stop if the bit vibrates, overheats or shows damage.
