Countersink drill bit Yato YT-44721 6.3 mm 1 pc

The Yato YT-44721 6.3 mm countersink drill bit is designed to create a clean conical recess for screw heads. Manufactured to deliver consistent diameter and angle, this countersink enables flush or recessed screw installation in both wood and metal substrates. The tool’s construction emphasizes durability and dimensional stability to maintain cutting geometry during repetitive use.

Advantages

This 6.3 mm countersink offers precise centring and a smooth conical finish, reducing the need for additional manual sanding or reaming. Its robust construction resists wear, allowing for prolonged service life under typical woodworking and light metalworking conditions. The bit is compact and easy to handle, facilitating controlled drilling and accurate placement of fasteners.

Suitable for

• Creating conical recesses for flat-head or countersunk screws in wood
• Preparing screw seats in thin sheet metal and light metal components
• Finishing and deburring the entry point of pilot holes
• DIY furniture assembly and repair tasks

Key specifications

• Countersink diameter: 6.3 mm
• Intended use: creating conical recesses for screw heads
• Suitable materials: wood and light metals
• Quantity: 1 piece
• Design: single-point countersink for accurate centring and finish

How to use

Mark the screw position and drill an appropriate pilot hole first if required by the screw size and material. Secure the workpiece to prevent movement. Fit the countersink into a compatible drill chuck and set a moderate speed; apply steady pressure and advance the bit into the material until the screw head sits flush with the surface. Withdraw the bit while the drill is running slowly to avoid material tearing. Inspect the recess and adjust depth with additional brief passes if necessary.

Usage recommendations

Use cutting lubricant or coolant when working with metals to reduce heat and extend tool life. For best results in wood, perform a test cut on scrap material to confirm fit and depth before working on the final piece. Wear appropriate eye protection and clamp the workpiece securely.
