Somta Long Series Drill - HSS-E Parabolic Flute - 1.4mm

Conquer deep-hole projects with the Somta Long Series Drill - HSS-E Parabolic Flute - 1.4mm. Designed for demanding metalworking tasks, this drill delivers precision where it matters most: through thick materials and long reaches that standard bits can’t handle.

Why this drill stands out

• Long-length advantage provides ample reach for through-thick workpieces, blind holes, and deep pockets without sacrificing rigidity or accuracy.
• HSS-E construction combines outstanding toughness with heat resistance, ensuring durable performance under high-speed drilling and sustained use in metals such as steel, stainless steel, aluminum, and brass.
• Parabolic flute design accelerates chip evacuation and reduces cutting forces. The result is steadier cuts, less clogging, and cooler operation—helping you maintain hole quality from start to finish and extend tool life.
• Sharp, precise cutting edges produce clean entry and true-diameter holes, minimizing wander and improving consistency across multiple holes in a single workpiece.
• Efficient heat management the flute geometry minimizes friction and heat buildup, reducing thermal distortion and helping you stay productive for longer sessions.

This 1.4mm drill is ideal for applications where small-diameter precision holes are required in thick or dense materials. Use it on drill presses or CNC machines with appropriate coolant to maximize life and performance. Start with a modest feed and moderate speed, and let the parabolic flute carry away chips as you work deeper—eliminating chip packing and maintaining smooth cutting action.

Perfect for: precision metal fabrication, electronics enclosures, mechanical housings, and any project needing tight, deep holes with clean edges. If you’re tackling long holes or navigating through layers of material, the Somta Long Series Drill delivers reliability, accuracy, and endurance in one compact tool.
