The CMT 822.033.11B 4-Wing Cut Out Slot Cutter for Solid Surfaces is a precision-engineered routing bit designed specifically for carving out undermount bowl openings in composite and solid surface materials. Built with four tungsten carbide-tipped cutting edges and equipped with a non-marring Delrin bearing, this cutter delivers clean, accurate cutouts while protecting the workpiece surface from damage. Sized at 3 5/8" in diameter with a 1/4" cutting height and a 1/2" shank, it is purpose-built for hand-held router use where control and surface quality are critical.

Key Features

• 4-Wing Tungsten Carbide-Tipped Cutting Edges - four hardmetal cutting wings distribute the cutting load evenly, resulting in a smoother cut, reduced vibration, and longer tool life when routing solid surface composites.
• Non-Marring Delrin Bearing - the bearing rides along the workpiece without scratching or marking the surface, preserving the finish of expensive solid surface material during the cutout process.
• 3 5/8" Cutting Diameter - sized to produce the large-format openings required for undermount bowl installations in solid surface countertops, reducing the need for secondary finishing passes.
• 1/4" Cutting Height (I) with 27.38mm Cutting Depth - these controlled cutting dimensions allow the bit to engage the material at a precise depth, helping ensure consistent slot geometry around the full circumference of the cutout.
• 1/2" Shank - the robust 1/2" shank provides a secure, rigid connection in standard router collets, minimizing deflection and improving cut accuracy in demanding solid surface routing applications.
• Right-Hand (RH) Rotation - compatible with standard right-hand rotation routers, making setup straightforward with no special tooling required.
• HW (Hardmetal/Carbide) Material Construction - the carbide-tipped cutting geometry maintains its edge longer than high-speed steel alternatives, reducing the frequency of tool changes during production runs.
• 3 1/4" Total Length - the overall bit length provides adequate clearance for reach into recessed or framed areas without requiring extended-reach arbors in most hand-held router setups.

Why This Product

• Purpose-Built for Solid Surface Undermount Cutouts - unlike general-purpose slot cutters, this bit is specifically designed for carving undermount bowl openings in composite solid surface panels, so the diameter, cutting height, and bearing configuration are all matched to that task without modification.
• Surface Protection Where It Counts - the non-marring Delrin bearing means the bit guides along finished solid surface without leaving scratches or impressions, which matters when working on countertop installations where surface quality is the final product.
• Four Cutting Wings for Cleaner Results - with four tungsten carbide-tipped wings rather than two, each pass removes material more evenly, helping produce a cleaner slot edge in composite material and reducing cleanup time.
• Hand-Held Router Compatible - designed for use on hand-held routers, this bit is a practical field and shop tool for countertop fabricators who need a reliable, controlled cutter without requiring a dedicated CNC setup.

Frequently Asked Questions

What type of material is this slot cutter designed to work with?

This cutter is specifically designed for solid surface composite materials. According to the product data, it is intended for carving out undermount bowl openings in composite solid surface panels using a hand-held router.

What is the purpose of the Delrin bearing included on this bit?

The Delrin bearing is a non-marring guide bearing, meaning it rides along the edge of the workpiece without scratching or marking the finished surface. This is especially important when working on solid surface countertops where preserving the surface appearance is essential.

What shank size does this bit require, and what type of router can it be used with?

This bit uses a 1/2" shank and is designed for use on hand-held routers equipped with a standard 1/2" collet. It rotates in the right-hand (RH) direction, which is standard for most handheld router models.

How many cutting edges does the 822.033.11B have, and what are they made of?

This cutter features four cutting wings (Z=4), each tipped with tungsten carbide (HW hardmetal). The four-wing configuration distributes cutting forces more evenly than two-wing designs, contributing to smoother cuts and longer edge retention in composite solid surface material.
