Product Description
CMT 316.050.11 Countersink for 4 Flute Drills by CMT is a precision carbide-tipped countersink designed to pair with 4-flute drill configurations, delivering clean, accurate countersinking at a 45 deg. cutting angle in a single efficient operation. With a 16mm working diameter and a compact 15mm total length, this right-hand rotation tool is engineered for tight-tolerance boring and countersinking in wood-based panel materials. The 5mm bore diameter fits standard machine spindles used in CNC boring centers and multi-spindle panel processing equipment, making it a reliable choice for production woodworking and cabinetry applications.
Key Features
- Hard Metal (HW) Carbide Construction - tungsten carbide material provides long-lasting cutting edge retention, reducing tool changes and downtime in production environments.
- 45 deg. Cutting Angle - produces a precisely angled countersink seat that ensures flush, professional screw or fastener seating without secondary hand finishing.
- 16mm Diameter with 5mm Bore - sized for compatibility with standard machine spindle chucks, allowing drop-in installation on common boring machine configurations without adapters.
- Compact 15mm Total Length - the short overall length reduces tool deflection and vibration during operation, supporting cleaner countersink geometry and consistent results across repeated passes.
- Right-Hand (RH) Rotation - matches the standard spindle direction of CNC boring centers and multi-spindle machines, eliminating the need for reversed spindle setups.
- 2-Tooth Cutting Configuration - dual cutting edges maintain a balanced cutting load, helping produce smooth, uniform countersink profiles in chipboard, MDF, hardwood, and similar panel materials.
Why This Product
- The 45 deg. countersink angle combined with hard metal carbide construction means woodworkers and cabinet manufacturers get precise, repeatable screw seats in panel materials without sacrificing edge quality or tool longevity.
- The 5mm bore diameter is designed to mount directly on standard boring machine spindles, saving setup time and eliminating the cost and complexity of adapter hardware.
- At just 15mm in total length, this countersink fits comfortably in multi-spindle heads with limited z-axis clearance, making it practical for dense production boring configurations.
- CMT hard metal tooling is purpose-built for industrial woodworking machines, offering a reliable option for operations running chipboard, MDF, plywood, and coated panels at higher feed rates.

Frequently Asked Questions
What cutting angle does the CMT 316.050.11 countersink use?
This countersink features a 45 deg. cutting angle, which creates a standard angled seat suitable for flush fastener installation in wood-based panel materials such as MDF, chipboard, and plywood.
What bore diameter does this countersink have, and what machines does it fit?
The CMT 316.050.11 has a 5mm bore diameter. This dimension is compatible with standard spindle chucks on CNC boring centers, multi-spindle boring machines, and panel processing centers that accept 5mm shank tooling.
How many cutting teeth does this countersink have, and why does that matter?
This tool has 2 cutting teeth. The dual-tooth configuration distributes cutting load evenly across both edges, helping produce a balanced, smooth countersink profile and reducing the risk of tool chatter or uneven seating in the workpiece.
Is this countersink compatible with right-hand spindle rotation machines?
Yes. The CMT 316.050.11 is designed for right-hand (RH) rotation, which is the standard direction for the majority of CNC boring centers and multi-spindle panel processing machines. No spindle reversal or special setup is required for typical installations.
