Twist Drill — Extra Long HSS‑G Drill (Ø 8 mm, 135° Tip, Bright Finished, Fully Ground Shank, DIN 1869)

A Twist Drill designed for deep metal drilling in Drilling Machines, offering an extra long length and a 135° tip for reliable penetration.

• Ø 8 mm for precise hole diameters
• Extra Long design for deep or hard‑to‑reach holes
• HSS‑G material for high wear resistance
• 135° tip angle for harder materials
• Fully Ground shank for high runout accuracy

Exceptional deep‑hole performance for demanding metalwork

This extra long HSS‑G Twist Drill is engineered to reach depths that standard drills cannot. The extended overall length and increased spiral length allow clean chip evacuation during deep drilling, reducing the need to retract frequently. As a result, the tool achieves efficient progress in tasks such as structural steel or thick plate drilling, where depth and steady feed are crucial. The DIN 1869 compliance guarantees suitable geometry for deeper holes under challenging conditions.

Faster cutting with lower feed forces thanks to precision grinding

A fully ground geometry and CNC‑refined flutes give the bit a sharp profile that cuts more efficiently. The ground design enables up to 40% faster drilling and requires significantly less axial force compared with rolled HSS bits, which is particularly beneficial for handheld or smaller drilling machines where operator control matters. The 135° Tip improves centring and reduces walking on hard substrates, helping to produce cleaner bores with less rework.

Robust material choice and targeted applications

Made from HSS‑G, this Twist Drill is suited for alloyed and unalloyed steel, cast steel, grey cast iron, sintered iron, non‑ferrous metals and hard plastics. The material selection balances hardness and toughness for high performance in metalworking. For stationary drilling with coolant and controlled feeds the bit excels; note that ground drills can be more brittle, so proper clamping and cooling extend tool life and maintain hole quality.

Designed for accuracy and machine compatibility

The bright finished surface and fully ground shank ensure consistent clamping and minimal runout, supporting precise machining outcomes. The geometry tailored by the DIN 1869 standard promotes repeatable centring and stability in common Drilling Machines. Users seeking clean, concentric holes with reduced radial deviation will benefit from the bit's tight manufacturing tolerances and sharp cutting edges.

FAQ

What materials is the MetavCUT Twist Drill suitable for
The MetavCUT Twist Drill is intended primarily for metals such as alloyed and unalloyed steel, cast steel and grey cast iron; it is also usable in non‑ferrous metals and hard plastics, delivering accurate holes when used with appropriate coolant and feed rates.

How should the MetavCUT Twist Drill be used to maximise tool life
For best results with the MetavCUT Twist Drill, use steady feeds, adequate clamping and cutting fluid for heat removal; the ground HSS‑G geometry cuts efficiently but benefits from controlled machining conditions to avoid chipping.

For what is a Twist Drill used
A Twist Drill is mainly applied when machining high‑strength materials and larger diameters. This form is easy to regrind and withstands higher loads while enabling deep, precise holes under demanding conditions.

Which three drill types exist
There are three main drill types: Metal drills, Wood drills and Stone/Concrete drills.

Why are Twist Drills pointed
Pointing reduces the cross‑cut at the tip. By re‑pointing, friction forces are significantly lowered so that less feed force is required and the tip centres more reliably in the workpiece.

Can a Twist Drill be used for wood
A metal Twist Drill can be used in wood but offers poorer guidance and a less clean finish; however, these drills are easier to regrind and have less aggressive self‑feeding than specialised wood bits.

At which depths is the Twist Drill most used
A through hole in solid material is typically made with a Twist Drill. For diameters up to 20 mm and drilling depths up to 100 mm, the Twist Drill is the most commonly used tool.
