Product Description
CMT Xtreme Plunge CNC Cutter with Insert Knives - 1 5/8 in. Diameter, 20mm Shank by CMT Orange Tools is a heavy-duty rotating insert-knife cutter built for CNC machining centers requiring direct plunge entry and rapid stock removal across wide surface areas. Featuring a 2 + 2 knife configuration - two dedicated plunging knives and two two-sided reversible insert knives secured by special Torx screws - this 20mm shank cutter delivers a clean, improved finish at the bottom of each cut. Designed for routing hardwood, softwood, plywood, MDF, chipboard, laminates, and plastics, it is a high-performance solution for production-level slot routing and pocket cutting operations.
Key Features
- 2 + 2 Insert Knife Configuration - Two plunging knives and two two-sided reversible insert knives work together to enable direct plunge entry into the workpiece without pre-drilling, making it efficient for pocket and slot routing operations on CNC machining centers.
- Two-Sided Reversible Insert Knives - Each knife can be flipped to expose a fresh cutting edge, effectively doubling the usable life of each knife and reducing per-cut tooling costs in production environments.
- Torx Screw Fastening - Special Torx screws lock the insert knives firmly in place during high-speed CNC operation, maintaining accurate knife positioning and safe, reliable performance cut after cut.
- 1 5/8 in. Cutting Diameter - A wide cutting diameter enables fast material removal over a large surface area in a single pass, reducing cycle time on CNC machining centers.
- 30mm Cutting Height - A generous cutting height accommodates workpieces and material thicknesses common in cabinetry, furniture, and panel processing applications.
- Right-Hand Rotation - Standard right-hand rotation is compatible with the vast majority of CNC router spindles, ensuring straightforward installation without special setup requirements.
- HW (Hardwood) Grade Tooling Material - Constructed with hardwood-grade (HW) insert knife material to maintain sharp cutting edges through dense hardwoods, plywood, MDF, and composite panel materials.
- 100mm Overall Length - A 100mm body length provides the reach and clearance needed for deep pocket routing and slot cutting in thick panel stock.
Why This Product
- Direct plunge capability without pre-drilling - The 2-plunging-knife design allows the cutter to enter material from the surface, eliminating the need for pre-drilled entry holes and speeding up CNC pocket routing workflows.
- Lower long-term tooling cost through reversible knives - Two-sided insert knives can be flipped for a second cutting edge, reducing how frequently knives need to be replaced in high-volume production settings.
- Improved bottom-of-cut finish - The insert knife geometry is specifically designed to leave a cleaner, improved surface at the bottom of the cut, reducing or eliminating secondary sanding or finishing steps on routed pockets and slots.
- Broad material compatibility for panel processing - Rated for hardwood, softwood, plywood, MDF, chipboard, laminates, and plastics, making it a versatile single-tool choice for shops processing a variety of panel materials on CNC machining centers.

Frequently Asked Questions
Can this cutter plunge directly into the material without a pre-drilled entry hole?
Yes. The CMT 653.001.11 is specifically designed with 2 dedicated plunging knives that allow it to enter the material directly from the surface, making it ideal for CNC pocket routing and slot cutting without pre-drilling.
How do the insert knives extend the life of this cutter?
The insert knives are two-sided and reversible. When one cutting edge becomes dull, the knife can be flipped to expose a fresh edge, effectively providing two usable cutting edges per knife and lowering tooling replacement costs in production environments.
What shank size does this cutter require, and is it compatible with standard CNC router spindles?
This cutter has a 20mm shank diameter and is designed for use on CNC machining centers equipped with a 20mm collet. It rotates right-hand (RH), which is the standard direction for most CNC router spindles.
What type of fastener is used to secure the insert knives, and why does it matter?
The insert knives are secured with special Torx screws. Torx fasteners provide a more secure grip than standard hex screws under the high-speed rotational forces of CNC routing, keeping knives firmly locked in position for safe and accurate cutting performance.
