Characteristics of TCT straight knife

Seven TCT Straight Cutter Features

TCT straight cutter features combine a tough steel body with brazed tungsten-carbide cutting edges. The steel shank and body tolerate normal routing loads, while carbide provides greater hardness and wear resistance than ordinary tool steel. This construction offers a practical balance of durability, cutting performance, diameter range, and cost.

Straight edges create flat groove bottoms, vertical pocket walls, rebates, slots, and trimmed edges. Different diameters, cutting lengths, flute counts, relief angles, and tip grades suit wood, plywood, MDF, particleboard, laminates, plastics, and some nonferrous materials. The brazed design also supports larger profiles that would be expensive or impractical in solid carbide.

Other TCT straight cutter features include resharpenable edges, generous chip space, and compatibility with common router collets. Performance still depends on accurate brazing, edge symmetry, balance, and low runout. Keep projection short, use secure workholding, and match speed, feed, pass depth, and chip extraction to the material. Inspect carbide tips, brazed joints, shank grip, heat, sound, and guard clearance before machining. A trusted cutting tool supplier can recommend suitable geometry. General router principles support clean cuts, long tool life, and safe operation.
