Twist Drill — Twist Drill 5.5 mm | Extra Long | HSS‑G | 135° | Bright Finished

The Twist Drill is an extra long HSS‑G metal drill bit (5.5 mm) designed for deep, precision drilling in hardened and unalloyed steels and other demanding materials.

• Extra long geometry for deep holes
• 135° tip angle for harder materials
• Fully ground shank for high concentricity
• HSS‑G material for fast cutting in metal
• Conforms to DIN 1869 for deep‑hole performance

Superior Cutting Performance for Tough Metals

The HSS‑G construction delivers a combination of hardness and toughness that enables faster chip removal and longer edge life when working with metal. The 135° tip angle reduces walking on hard surfaces and improves entry when drilling stainless steel or tempered materials. This geometry is particularly effective for tasks where a clean, precise hole is required rather than aggressive material removal.

Designed for Deep and Hard‑to‑Reach Holes

With an extra long overall length and a deep‑spiral flute design, this drill is optimised for extended reach in installations and fixtures. The extended spiral length supports reliable chip evacuation during deep drilling, lowering the risk of clogging; this makes the bit suitable for deep bore operations in components where access is limited or standard lengths are insufficient.

Precision Shank and Stable Runout

A fully ground shank and CNC‑ground flute geometry ensure high concentricity and precise cutting edges. The ground manufacturing process yields sharper cutting lips and improved dimensional accuracy, producing cleaner holes in metal. For stationary or machine use with adequate cooling, the ground finish provides superior performance over rolled alternatives.

Practical Application and Material Range

This Twist Drill is engineered primarily for metalworking: legated and unlegated steel, cast iron, sintered iron, non‑ferrous metals and hard plastics. The DIN 1869 standard and the HSS‑G specification indicate suitability for drilling into materials up to 1000 N/mm² when operated under appropriate speeds and coolant conditions. For less critical tasks or soft materials, consider standard‑geometry drills for easier guidance.

Who Benefits Most from This Tool

Workshop professionals, maintenance technicians and machine operators who require dependable performance for deep metal drilling will benefit from the combination of extra length, high cutting speed and precision finish. The bit is suitable for use in a Drilling Machine or robust hand drilling equipment, provided speed and feed are adapted to material and cooling is used for sustained tool life.
