Definition: The basic edge-forming bit, the corner-rounding bit rounds an edge to a given radius. The tool is shouldered to cut a fillet. The cut can be used to ease edges, as a simple profile, or as a part of a complex one. Also known as roundover, rounding over, and quarter-round. If a smaller pilot bearing is used, a second shoulder can be produced, in effect making the bit a beading bit.

Extra Information
- The CKP1204 creates a 3/8 inch radius corner round profile.
- The bit has a 1/4 inch shank and should only be used in a compatible router collet.
- Ensure that at least 3/4 of the shank length is inserted into the router collet.
- Do not bottom-out the bit in the collet. Leave approximately 1/8 inch clearance from the bottom of the collet.
- When removing larger amounts of stock, route in two or more passes for better control and finish.
- For outside edges, feed the router anti-clockwise. For inside edges or frames, feed clockwise when using a portable router.
- Suggested maximum router speed for a 1.25 inch diameter bit is 18,000 RPM, but always follow the router manufacturer’s guidance.
Pro Tips
- Test the profile on a scrap piece of the same material before routing the final workpiece.
- Use shallow passes rather than removing too much material in one cut, especially with the larger 3/8 inch radius.
- Keep the router base flat and steady against the workpiece to avoid uneven edges.
- Make sure the bearing is clean and spins freely before use.
- Use a router table and fence whenever possible for better control and repeatable results.
How to Use
- Make sure the router is switched off and unplugged before fitting the bit.
- Insert at least 3/4 of the shank length into the router collet, leaving about 1/8 inch clearance from the bottom.
- Tighten the collet securely according to the router manufacturer’s instructions.
- Set the cutting depth to achieve the required 3/8 inch round-over profile.
- Secure the workpiece firmly before routing.
- Start the router and allow it to reach full speed before contacting the workpiece.
- Feed the router steadily in the correct direction and avoid forcing the bit.
- Switch off the router and wait for the bit to stop completely before removing it from the workpiece.
Safety
- Always use the correct router bit for the job.
- Using any tool can be dangerous when incorrect procedures are followed.
- Always wear eye and ear protection when using a router.
- Wear suitable gloves when handling the bit, as the cutting edges are sharp.
- Follow all safety and use instructions supplied with your router.
- Never use router bits that are dull, damaged or visibly worn.
- The bit can become hot after use; allow it to cool before handling.
- Do not force the bit or overload the router.
- Use a router table and fence whenever possible, especially with larger diameter bits.

Explaining
the Specifications:
- (d) -> The diameter of the shank or shaft. This size should be the same as the collet size of your router. Example: a small router is mostly supplied with a quarter inch collet that is 6,35 mm inside diameter.
- Common collet sizes:
- 1/4" collet = 6,35mm inside diameter
- 8mm collet = 8mm inside diameter
- 12mm collet = 12mm inside diameter
- 1/2" collet = 12,7mm inside diameter
- NOTE that the 12mm and
the 12,7mm (1/2") sizing are often misunderstood. 1/4 inch is not 6mm but
e
xactly
6,35mm. A 6mm shank will not fit in a 1/4 in collet. Wrong sizes will either
break the collet or the bit will fall out.
- TCT = Tungsten Carbide Tipped
- Allways stay in the MAX Speed range of router bit
