Yato YT-44770 drill bit

Yato YT-44770 drill bit is a single titanium-coated metal drill with a hexagonal shank, designed for professional use. Manufactured from high-speed HSS steel, the drill has a split point and ground cutting edges with a 135° point angle to enable accurate starting and efficient drilling in hard and stainless steels.

Advantages

The titanium coating increases surface hardness and reduces friction for longer tool life. The split point design allows drilling without pilot holes and minimizes walking at startup. Ground cutting edges and the 135° angle improve chip evacuation and heat dissipation during high-load drilling in hard materials.

Suitable for

• Drilling in high-grade stainless steel
• Drilling in structural steel
• Drilling in cold-rolled steel
• Professional metalworking and construction tasks

Key specifications

• Material: high-speed HSS steel with titanium coating
• Shank type: hexagonal
• Point type: split point, 135° point angle
• Cutting edges: ground
• Pack quantity: 1 piece

How to use

Secure the hexagonal shank in a compatible drill chuck or driver. Mark the drilling position, apply moderate pressure, and start at low speed to ensure the split point engages without walking. Increase speed and feed appropriate to the material being drilled, using cutting fluid when machining stainless or hard steels to improve cooling and prolong drill life.

Usage recommendations

Use suitable personal protective equipment, clamp the workpiece, and apply cutting fluid for stainless and hard steels. Replace the drill bit when wear degrades cutting performance.
