Series 6236
Insert tool for routing deep mortise pockets in composite and solid wood. This tool is primarily used for lock pocket cutouts. Tool body is made of a special heavy metal material that provides rigidity and prevents flexing during machining. Insert knife design provides constant diameter. This tool uses 2 offset insert knives (Style A&B) for 16 and 18mm diameter tools, and for 14mm diameter, Style C &D. RH Rotation.

Mortise Insert Router Bit - Lock Pockets/Deep Cuts
Product FAQs
Deep mortising can place substantial lateral forces on a cutting tool. The special heavy-metal body provides additional rigidity to help reduce tool deflection and maintain dimensional accuracy during deep machining operations.
Replaceable inserts allow worn cutting edges to be changed without replacing the entire tool body. They also maintain a constant cutting diameter, avoiding the gradual diameter reduction that can occur when conventional tools are repeatedly sharpened.
Series 6236 is available in 14 mm, 16 mm and 18 mm cutting diameters. Different offset insert styles are used depending on the tool diameter. Custom size tools can be made to customer requirements.
The recommended spindle-speed range is 12,000–18,000 RPM. Actual machining parameters should be matched to the tool diameter, material, depth of cut, machine and workholding.
Maximum Cut Progression:Â 8-10mm in solid wood and up to 15mm in other wood-based materials like MDF and Particleboard.
Yes. Replacement insert knives, screws and the appropriate Torx key are available separately. The required insert style depends on the selected cutting diameter.
Yes. Weldon shank modifications are available for applications requiring additional resistance to tool movement or slippage within the toolholder.
The mortise insert router bit Series 6236 is engineered for deep mortising applications where tool rigidity, dimensional accuracy and efficient material removal are critical. It is particularly well suited for machining lock pockets, deep mortises and other recessed CNC routing applications in solid wood and wood-based materials.
Deep pocket routing places significant lateral forces on a cutting tool, particularly when machining at extended cutting depths. Series 6236 features a special heavy-metal tool body designed to increase rigidity and minimize tool deflection during machining. This helps maintain dimensional accuracy and consistent cutting performance throughout the mortise.
Replaceable Insert Design
The replaceable carbide insert design provides an important advantage over conventional solid tooling. Worn cutting edges can be replaced without replacing the complete tool body, reducing long-term tooling costs.
Two offset insert knives create the cutting geometry while maintaining a constant cutting diameter. Different insert styles are used according to the selected tool diameter.
The replaceable insert system also eliminates the diameter reduction that can occur when conventional cutting tools are repeatedly sharpened—an important consideration when machining lock pockets and other mortises to precise dimensions.
Designed for Deep CNC Mortising
The mortise insert router bit is available in 14 mm, 16 mm and 18 mm diameters and is designed for right-hand rotation.
Recommended spindle speeds range from 12,000–18,000 RPM. Maximum material removal per pass depends on the material and application. A gradual plunge should be used when entering and exiting the cut.
Weldon shank modifications are available for applications requiring additional resistance to tool slippage within the holder.
