Drill bit YATO YT-44860, single piece

YATO YT-44860 drill bit supplied as a single piece, made from high-speed steel for professional drilling in high-grade stainless steel, structural steel, INOX and cold-rolled steel. It is intended for use with standard drills that accept 1/4" HEX (6.3 mm) shanks and is suitable as a replacement or spare bit for workshop and construction tasks.

Advantages

The HSS material provides higher drilling speed while preserving resistance to wear and damage and keeping the drill geometry stable. A cross-blade split point with a 135° apex angle enables drilling without pre‑marking and improves centring. Precisely ground surfaces and edges made to DIN 338 standard ensure accurate hole dimensions. The design promotes rapid heat dissipation during drilling in hard steels and reduces friction and the adhesion of swarf to the bit. Manufactured from a single piece of HSS 6542 steel for improved strength and durability.

Suitable for

• Drilling in high-grade stainless steel and INOX
• Drilling in structural and cold-rolled steel
• Workshop and construction drilling tasks
• Replacement or spare drill bit for compatible drills with 1/4" HEX shank

Key specifications

• Material: high-speed steel (HSS 6542)
• Point type: cross-blade split point, 135° apex angle
• Shank: 1/4" HEX (6.3 mm)
• Manufacturing standard: ground to DIN 338
• Construction: single-piece design

How to use

Secure the YATO YT-44860 drill bit in a compatible drill chuck or hex holder that accepts 1/4" HEX shanks. Mark the drilling location if required, align the split point with the workpiece, and apply steady, even pressure while drilling at an appropriate speed for the material. Use cutting fluid or coolant when drilling stainless and other hard steels to improve heat dissipation and prolong tool life. Withdraw the bit periodically to clear swarf and avoid clogging.

Usage recommendations

For best results when drilling stainless and high-strength steels, use moderate drilling speeds, apply cutting fluid, and avoid excessive axial force. Inspect the bit for wear before use and replace it if the cutting edges become dull to maintain hole quality and safety.
