Somta Extra Long Series Drill - HSS-E Parabolic Flute - 5mm x 195mm

Introducing the Somta Extra Long Series Drill - HSS-E Parabolic Flute - 5mm x 195mm. Built for deep-hole precision, this drill bit pairs extended reach with reliable performance for demanding drilling tasks.

Key design advantages:

• Extended reach for deep holes: With a 195mm overall length and a 5mm diameter, this bit lets you bore deep into workpieces without re-positioning or flipping the part, saving setup time and improving hole alignment.
• HSS-E construction: The High-Speed Steel-E body delivers strong hardness and heat resistance, extending tool life even in tougher metals and longer drilling cycles.
• Parabolic flute for efficient chip evacuation: The parabolic flute geometry channels chips away from the cutting edge, reducing clogging and allowing steadier feeds and faster breakthrough in thick materials.
• Sharp cutting edges and low friction: Precisely honed edges and flute geometry minimize friction and heat buildup, helping you achieve clean, accurate holes with minimal deflection.

Ideal applications include deep-hole drilling in metalworking environments such as automotive fabrication, machinery maintenance, and general fabrication where access is limited or the workpiece is thick. This drill excels in through-holes and blind holes where straightness, roundness, and positional accuracy matter.

How this compares to standard-length bits: the extended flute length and parabolic design reduce the need for frequent bit changes, improve chip clearance in long hole runs, and maintain stable cutting conditions as hole depth increases. For best results, use steady feeds, moderate speeds appropriate to the material, and cooling/lubrication to further extend tool life.

Who should choose the Somta Extra Long Series Drill? shop floor machinists, tool rooms, CNC operators, and engineers who routinely drill deep, precise holes in steel, aluminum, or other metals while maintaining roundness and surface finish. It’s a dependable workhorse when reach and durability matter more than compact tooling.
