Cylindrical round-end router bit Dedra C12x25 mm, shank 6 mm

Cylindrical round-end router bit Dedra C12x25 mm, shank 6 mm is a woodworking cutter designed for shaping, slotting and contouring work. The tool has a 12 mm cutting diameter and 25 mm cutting length with a rounded end that allows smooth transitions when forming grooves, profiles and edge radii. It fits routers and CNC machines with a 6 mm collet and is intended for general routing tasks in soft and hardwood, plywood and composite panels.

Advantages

The solid design provides consistent cutting performance and reduced vibration during operation. The rounded tip produces clean, burr‑free contours and minimizes tear‑out on delicate surfaces. A 6 mm shank ensures compatibility with common compact routers and CNC spindles, while the 25 mm cutting length offers enough engagement for shallow to medium-depth passes. The bit’s geometry balances material removal and surface finish for efficient routing.

Suitable for

• Shaping and profiling edges on furniture components
• Cutting grooves and slots for joinery and inlays
• Contour trimming and finishing of routed surfaces
• Detail work on mouldings and decorative panels

Key specifications

• Cutting diameter: 12 mm
• Cutting length: 25 mm
• Shank diameter: 6 mm
• Tip type: round/end radius for curved profiles
• Suitable tool types: handheld routers, router tables, CNC machines with 6 mm collet
• Typical materials: softwood, hardwood, plywood, MDF, laminates, common composites

How to use

Secure the 6 mm shank firmly in the router collet and check runout before starting. Adjust router speed and feed rate according to material density and desired finish: higher speeds and lighter passes for clean edges, slower feeds for heavy cuts. Make multiple shallow passes rather than one deep cut to reduce load on the bit and improve surface quality. Use appropriate clamps, guides or fences for accurate profiling and maintain steady, even feed to avoid burning or chipping.

Usage recommendations

For prolonged tool life, keep the cutting edges clean from resin and pitch, sharpen or replace the bit when signs of dulling appear, and use dust extraction where possible to protect both the cutter and the workpiece. Select feed and speed settings that match the chosen material and router power.
