The Somta Long Series Drill - HSS-E Parabolic Flute - 7.2mm is built for deep-hole precision, delivering clean, accurate holes even when you’re drilling through thick materials. This long-reach drill bit combines performance-focused geometry with industrial-grade durability to tackle the toughest drilling tasks with confidence.
Why this drill stands out
- Long reach for deep holes—designed to access hard-to-reach areas and through-thick stock without retooling or multiple setups.
- HSS-E construction—high-speed steel enhanced for superior wear resistance and heat tolerance, keeping cutting edges sharp longer under demanding work conditions.
- Parabolic flute design—efficient chip evacuation reduces cutting forces and heat buildup, minimizing tool deflection and promoting steadier, more stable drilling.
- Sharp cutting edges— dependable profile that produces clean, precise holes with tight diameter control and minimal burrs.
- Friction-reducing flute geometry— helps keep temperatures down during extended drilling cycles, extending tool life in tough materials.
Ideal applications
- Machining thick plates and through-holes in steel, stainless steel, cast iron, and other common engineering materials.
- Projects requiring deep-hole capability without compromising hole concentricity or finish.
- Fabrication, automotive, and machinery tasks where reach and reliability matter most.
Performance notes
Compared with standard-length drills, this long-series design maintains diameter accuracy while reducing chatter and tool flex during entry. The HSS-E composition handles higher cutting speeds more reliably, enabling productive drilling cycles and better surface finishes on challenging materials.
Practical tips for best results
- Use appropriate cutting fluid or lubrication to maximize edge life and heat management.
- Begin with a light, steady feed and increase pressure gradually to help maintain hole straightness.
- Clear chips regularly—consider peck drilling techniques to prevent chip buildup and overheating in long holes.
- Secure the workpiece firmly and align the drill straight to avoid deflection and maintain consistent diameter.
