Drill bit YATO YT-60402 — single piece, standard twist drill

YATO YT-60402 single-piece standard twist drill is a general-purpose 8 mm drill bit designed for use with compatible drills and drill drivers. Manufactured from carbon steel, this bit has a HEX 6.35 mm shank for secure seating in chucks and quick-change holders. It is suitable for both dry and wet drilling and is supplied as a single unit, making it convenient as a spare or replacement bit for routine drilling tasks.

Advantages

The drill bit combines a carbon steel body with a brazed diamond tip to increase cutting durability on challenging surfaces. Its HEX 6.35 mm shank ensures stable grip and reduces slippage in compatible chucks and bit holders. Rated for use up to 8000 rpm, the bit supports a range of drilling speeds, and its design permits effective performance in both dry and wet conditions.

Key specifications

How to use

Fit the HEX 6.35 mm shank into a compatible drill chuck or quick-change holder and secure it firmly. Choose drilling speed appropriate for the material—start at lower rpm for hard or brittle surfaces and increase as needed while maintaining control. For porous or abrasive materials use wet drilling where applicable to reduce heat and dust. Apply steady pressure without forcing the bit; withdraw periodically to clear debris and allow cooling.

Usage recommendations

Use with appropriate personal protective equipment including safety glasses and dust extraction when dry drilling. For best results on ceramic, porcelain and stone materials, prefer wet drilling to prolong bit life and improve hole quality. Inspect the bit before use and replace if wear or damage is visible.
