Linear Tools HSS Drill Bit, 5.5mm x 139mm, Black Finish

The Linear Tools HSS Drill Bit is a high-quality, high-speed steel (HSS) tool manufactured to DIN 338 and BS 328 standards, ensuring precision and durability. Its longer working length (91mm) compared to standard drill bits makes it especially useful for hard-to-reach applications where conventional drill bits fall short.

This drill bit features a fully ground HSS construction, providing excellent cutting performance and extended tool life. The 118° standard point ensures efficient penetration and smooth drilling across various materials.

Ideal Applications

• Drilling in tight or deep spaces where standard drill bits cannot reach
• General-purpose drilling in wood, metal, plastic, and other common materials
• Professional and DIY projects requiring extended reach
• Precision drilling where standard-length bits are insufficient
