Product Description
The CMT 315.200.11 Countersink for 2 Flute Drills is a precision-engineered tungsten carbide-tipped boring tool designed to drill and countersink in a single pass. Built for right-hand rotation and sized to accept drill diameters from 13/64 in. to 25/64 in., this 20mm diameter countersink integrates a 45 deg. cutting angle that delivers clean, flush-seated results in solid wood, chipboard, MDF, HDF, plywood, laminates, and coated panels. With a compact total length of 16.5mm and a bore diameter range of 5mm to 10mm, CMT's 315.200.11 is optimized for use in multi-spindle CNC boring machines, CNC boring centers, and panel processing centers where consistent hole quality and production efficiency are critical.
Key Features
- HW (Tungsten Carbide) Construction - hard-wearing carbide material maintains a sharp cutting edge through high-volume production runs on wood composites and laminates, reducing downtime from frequent tool changes.
- 45 deg. Cutting Angle - delivers a precise countersink geometry that ensures fastener heads sit flush or below the panel surface without additional finishing passes.
- 2-Flute Design - twin cutting edges provide balanced chip evacuation and smooth bore walls, minimizing tearout on coated panels and laminates where surface quality matters most.
- 20mm Diameter with 5mm to 10mm Bore Range - the wide bore diameter range (5mm to 10mm) accommodates multiple drill shank sizes, making this countersink adaptable across different machine configurations and dowel drill diameters from 13/64 in. to 25/64 in.
- Right-Hand (RH) Rotation - compatible with standard CNC boring spindles and multi-spindle boring machines, ensuring drop-in integration without special tooling modifications.
- Compact 16.5mm Total Length - the short overall length reduces spindle projection and vibration, contributing to more accurate hole positioning and longer machine bearing life during repetitive panel boring operations.
Why This Product
- Drill and countersink in one pass - combining the boring and countersinking operation into a single tool pass reduces cycle time on CNC boring centers and panel processing lines, improving throughput without sacrificing hole quality.
- Wide compatibility with popular drill shank sizes - the 5mm to 10mm bore diameter range means this countersink works with a broad range of 2-flute dowel drills (13/64 in. to 25/64 in.), reducing the number of dedicated tools required in a production setup.
- Carbide toughness matched to engineered wood materials - HW tungsten carbide construction handles the abrasive adhesives and resins found in chipboard, MDF, HDF, and laminated panels, sustaining cutting performance where high-speed steel tools would wear quickly.
- Right-hand rotation for standard CNC compatibility - the RH rotation designation aligns with the standard spindle direction on most multi-spindle CNC boring machines and boring centers, allowing straightforward installation and consistent operation across production environments.

Frequently Asked Questions
What drill shank sizes is the CMT 315.200.11 countersink designed to work with?
This countersink is designed for use with 2-flute drills having a diameter range of 13/64 in. to 25/64 in. The bore diameter of the countersink itself accommodates shanks from 5mm to 10mm, covering that full drill size range.
What cutting angle does the CMT 315.200.11 produce, and why does it matter for panel work?
The tool produces a 45 deg. countersink angle. This geometry is well suited for seating fastener heads flush with or below the surface of chipboard, MDF, plywood, and laminated panels, eliminating the need for a separate countersinking operation or secondary finishing step.
What type of machines is this countersink compatible with?
The CMT 315.200.11 is designed for use in multi-spindle CNC boring machines, CNC boring centers, panel processing centers, and boring machines fitted with an adapter or chuck. Its right-hand (RH) rotation matches the standard spindle direction found on these machine types.
What material is the cutting portion of this countersink made from?
The cutting portion is constructed from HW tungsten carbide. Tungsten carbide provides the hardness and wear resistance needed to maintain a sharp cutting edge through extended production runs on abrasive engineered wood materials such as chipboard, MDF, and laminate-faced panels.
