CMT Roundover Bit - 3/4 in. Radius - 1/2 in. Shank

CMT Round Over Bit – 3/4 in. Radius – 1/2 in. Shank

It’s hard to find a profile bit that gets more work than a Roundover Bit. This shape is great for simple tasks like easing sharp corners, or for more intricate jobs like drop leaf tables (when used in conjunction with our Cove Bits of the same radius).

The smaller bearing on the CMT Beading bits makes a delicate inset at the base of the cut, giving you the advantage of an extra decorative option. Be sure to keep the black bearing washer right side up to correspond with the bearing rotation when reassembling the bearing. Improper reassembly can cause the bit to unscrew. All CMT roundover bits have a 12,7mm (1/2") bearing diameter with the exception of the radius 28,6mm (1–1/8") and 31,7mm (1/4") bits which have a 19mm (3/4") bearing diameter. You have 13 different radii to choose from, the majority having 5 shank diameter options. All bits are made of Fatigue Proof® steel and have carbide–tipped cutting edges.

Bits featuring radius from 25,4mm (1") to 38,1mm (1–1/2") are to be used only on router table.

Safety tips: Always wear a dust mask and eye protection when routing.

Shop tips: The CMT 1,6mm (1/16") radius roundover bit is excellent for finishing laminates. Virtually eliminates the filing required when using conventional trim bits.

Safety precautions: never use damaged or worn bits. Always work at the recommended proper feed rate without forcing the bit. Pay particular attention when making the initial cut with a small diameter bit. For best results when working with small diameter bits, make the cut in more than one pass.

How CMT produces high quality router bits

• Turning, Milling and Cutting CMTs biggest investment in recent years has been in upgrading production. Today, all machinery at CMT is fully automated. CNC machines run by specially trained operators ensuring the shanks and bodies of our router bits and boring bits are accurate and perfectly balanced.
• Heat forged steel bodies for large diameter bits No router bits are exactly the same, not even in the way they are made. Certain bits require a few more steps than others, like heat forging the steel of larger diameter bits before turning it into precise bit bodies. This extra step produces a radial grain orientation which offers large diameter bits extra strength and durability.
• Brazing We have pioneered the art of brazing. Not only does our unique custom–designed computerized brazing equipment help eliminate the inconsistencies found in old fashioned hand brazing, but our silver–copper–silver brazing ‘sandwich’ provides a tight bond between the steel and the carbide, with a shock absorbing effect to protect the carbide tips when cutting harder woods.
• Specially formulated carbide for specific applications In woodworking, you have to cut every kind of material, so we make sure that our carbide tips can handle each individual
