Twist drill bit Yato YT-4140 1 pc 1.4 cm diameter

The Yato YT-4140 twist drill bit is a single-piece cutting tool with a 1.4 cm diameter designed for precision drilling in a range of workshop and maintenance tasks. Made for general-purpose use, this cylindrical-shank drill bit is intended to deliver accurate holes in cast iron, non-ferrous metals, plastics and stainless steel. The bit’s 160 mm overall length provides good reach for many standard drilling operations.

Advantages

This drill bit combines a robust single-piece construction with a twist geometry that helps evacuate chips efficiently and maintain cutting stability. The cylindrical shank ensures secure clamping in standard chucks and reduces runout for improved hole quality. Its 1.4 cm diameter is suited to both repair and fabrication tasks where a mid-sized bore is required.

Suitable for

• Drilling holes in cast iron components
• Creating openings in non-ferrous metals (aluminum, brass, etc.)
• Working with plastic parts and assemblies
• Drilling light-duty stainless steel applications
• General workshop, maintenance and fabrication tasks

Key specifications

• Type: twist drill bit
• Diameter: 1.4 cm
• Overall length: 160 mm
• Shank type: cylindrical
• Suitable materials: cast iron, non-ferrous metal, plastic, stainless steel
• Quantity: 1 piece

How to use

Select the Yato YT-4140 drill bit for the appropriate diameter and secure it in a compatible drill chuck, ensuring the cylindrical shank is fully seated and tightened. Use recommended spindle speeds and feed rates for the material being drilled; apply suitable cutting fluid when drilling metals such as stainless steel or cast iron to reduce heat and prolong tool life. Begin drilling with a steady, even pressure, clearing chips periodically to avoid clogging and overheating. Finish the hole with a deburring operation if required.

Usage recommendations

For best results, match drill speed and coolant to the material: lower speeds and cutting fluid for stainless steel and cast iron, moderate speeds for non-ferrous metals, and higher speeds for plastics. Inspect the bit for wear before use and replace when edges are blunt to maintain hole accuracy and safety.
