Drill bit YATO YT-44627 — pack of 2 pieces

YATO YT-44627 drill bit — pack of 2 pieces, designed for use with standard drill chucks. These HSS 4241 steel bits are intended for drilling into stainless steel, structural steel and cold-rolled steel. The set contains two long-length bits with a working length suitable for deeper holes while the shank diameter fits common 1/2" chucks; bits are supplied in plastic boxes for secure storage and transport. Check your drill chuck size and material compatibility before use.

Advantages

The HSS 4241 construction ensures improved cutting speed and retains drill geometry under load, increasing resistance to wear and dulling. A 135° split-point (cross-blade) tip enables drilling without prior center punching and improves centering on metal surfaces. The cutting geometry and surface finish reduce friction and help dissipate heat during drilling in hard steels, which lowers the risk of overheating and extends tool life. Supplied in protective plastic boxes for safe handling and storage.

Suitable for

• Drilling stainless steel parts
• Working with structural and cold-rolled steel
• Workshop repairs and maintenance
• Home DIY tasks requiring metal drilling
• Keeping as spare bits for professional toolkits

How to use

Secure the appropriate drill bit in a compatible 1/2" chuck and tighten firmly before operation. Select a drilling speed suited to HSS tools and the metal being worked; lower speeds for stainless and hard steels help reduce heat. Use cutting fluid or coolant when drilling thick or hard metal to improve chip evacuation and extend tool life. Apply steady, moderate feed pressure and avoid side loads that can damage the tip or break the bit. After use, clean chips from flutes and store the bits in their plastic boxes.

Usage recommendations

For best results when drilling stainless and structural steels, use a suitable cutting lubricant, start at a lower rpm to establish the hole, and increase speed gradually if cutting remains stable. Inspect bits for wear or damage before reuse and replace if geometry is compromised.
