Product Description
CMT 316.060.11 Countersink for 4 Flute Drills by CMT is a precision carbide-tipped countersink designed for use with 4-flute dowel drills in panel processing and woodworking applications. With a 45 deg. cutting angle and right-hand rotation, this integrated countersink delivers clean, accurate countersinking in chipboard, MDF, hardwood, and a wide range of engineered wood panels. Its compact 15mm total length and 6mm bore diameter make it well suited for multi-spindle CNC boring machines and boring centers where precision and repeatability are essential.
Key Features
- HW (Tungsten Carbide) Material Construction - hard carbide cutting edges maintain sharpness through demanding production runs, reducing downtime and replacement frequency in high-volume panel processing.
- 45 deg. Cutting Angle - matched to standard countersink geometry for fastener seating, ensuring flush or recessed screw heads without secondary hand-finishing operations.
- 16mm Cutting Diameter - sized to create a clean, proportional countersink around typical CNC boring hole patterns, eliminating oversized or undersized recesses.
- 6mm Bore Diameter - direct-mount compatibility with 6mm spindle tooling on multi-spindle boring machines, allowing quick changeover without adapters or custom holders.
- 2-Tooth Cutting Configuration - dual cutting edges balance cutting load evenly across the workpiece surface, reducing vibration and improving finish quality on coated panels and laminates.
- Right-Hand (RH) Rotation - standard rotation direction matches conventional CNC boring center spindles, ensuring immediate drop-in compatibility without reprogramming spindle direction.
- Compact 15mm Total Length - short profile minimizes spindle extension, improving rigidity and reducing deflection for tighter dimensional tolerances on finished workpieces.
Why This Product
- Purpose-built for 4-flute drill configurations, this countersink integrates directly into existing boring setups without requiring additional tooling stages or spindle changeovers, saving setup time on production lines.
- The 45 deg. carbide-tipped cutting angle delivers consistent countersink geometry in both solid wood and engineered panel materials, making it a reliable choice for furniture manufacturing and cabinet production environments.
- At just 15mm in total length with a 6mm bore, this tool is designed for tight spindle layouts on multi-spindle CNC boring machines where space between drill units is limited.
- HW carbide construction means longer tool life compared to HSS alternatives when cutting abrasive materials like MDF, HDF, and laminated chipboard - a direct reduction in per-unit tooling cost over time.

Frequently Asked Questions
What drill bore diameter does the CMT 316.060.11 fit?
The CMT 316.060.11 has a 6mm bore diameter, making it directly compatible with 6mm spindles commonly found on multi-spindle CNC boring machines and boring centers. No adapter is required for standard 6mm spindle configurations.
What is the cutting angle of this countersink, and why does it matter?
This countersink operates at a 45 deg. cutting angle. This geometry is matched to common fastener head profiles used in panel furniture and cabinetry, allowing screws to seat flush or recessed without additional hand-finishing after boring.
Is this countersink compatible with laminated and coated panels?
Yes. The HW (tungsten carbide) cutting edges are well suited for abrasive engineered materials including laminates, coated panels, MDF, and HDF - materials that would accelerate wear on lower-grade tooling. The 2-tooth configuration also helps maintain a clean entry on surface-sensitive coated panels.
What machines is the CMT 316.060.11 designed to work with?
This countersink is designed for use on multi-spindle CNC boring machines, CNC boring centers, panel processing centers, and boring machines equipped with a chuck or adapter. Its right-hand rotation and 6mm bore diameter are standard for these machine types.
