Countersink drill bit Yato YT-44724 1.24 cm diameter

The Yato YT-44724 1.24 cm diameter countersink drill bit is made for creating conical recesses that let screw heads sit flush with the workpiece. Designed for general-purpose use in woodworking and light metalworking, this countersink produces a clean, precise seat for flat-head screws and fasteners. Its solid construction provides consistent performance for repetitive drilling operations.

Advantages

This countersink drill bit offers accurate cone geometry for uniform countersinking depth and angle, reducing the need for rework. The bit is compatible with standard drill chucks and handheld drills, enabling easy attachment and use. Durable materials and a ground cutting edge deliver reliable cutting action and longer service life, while the compact diameter makes it suitable for small and medium fasteners where controlled countersinking is required.

Suitable for

• Creating countersunk holes for flat-head screws in wood
• Preparing recesses in sheet metal and light alloys
• Finish carpentry and cabinetry work requiring flush screw installation
• Maintenance and repair tasks where precise screw seating is necessary

Key specifications

• Type: straight countersink drill bit for countersinking operations
• Material: hardened tool steel with ground cutting edges
• Diameter: 1.24 cm (approx. 12.4 mm) cone diameter
• Intended use: woodworking and light metalworking
• Compatibility: standard drill chucks for handheld or bench drills

How to use

Mark the screw center on the workpiece and secure the material to prevent movement. Fit the countersink into a drill chuck and set the drill to a moderate speed appropriate for the material. Align the bit with the marked center, apply steady pressure, and drill until the desired recess depth is reached. Periodically remove swarf from the hole and inspect the fit of the screw head. For multiple identical holes, use a depth stop or mark the bit to ensure consistent countersink depth.

Usage recommendations

Use cutting lubricant or reduced speed when countersinking harder metals to extend bit life. Avoid excessive axial force to prevent chipping the cutting edge. Inspect the bit before use and replace if cutting edges become dull or damaged to maintain clean, precise results.
