Twist Drill — Drill Bit, Diameter 8 mm, 118° Tip Angle, HSS‑G, Fully Ground, Silver, DIN 338

The Twist Drill is a precision Drill Bit for metalworking, offering an 8 mm Diameter and a 118° Tip Angle for reliable centring and clean holes in a variety of metals.

• Ideal for metalworking applications with high precision
• Fully ground geometry for faster, cleaner drilling
• Hexagonal shank for secure torque transmission
• Conforms to DIN 338 for standardised short Twist Drills
• Suitable for use in Drilling Machines and handheld drills

Faster, cleaner holes thanks to fully ground geometry

The Twist Drill uses a Fully Ground HSS‑G construction that produces very sharp cutting edges and high runout accuracy. This manufacturing method (CNC grinding) enables up to 40% faster drilling and requires approximately 50% less feed force compared with rolled HSS bits, which translates into less operator fatigue and shorter cycle times. The grounded flute geometry also yields cleaner, more precise holes particularly in alloyed and unalloyed steel and other hard materials.

Secure clamping and improved torque transfer with a hexagonal shank

A Hexagonal Shank (sechskant) ensures form‑fit torque transmission into Bit Holders and quick‑change chucks, reducing slippage during heavy cutting. The shank design allows direct use in 1/4" bit holders (E6.3) while remaining compatible with standard chucks, which simplifies tool changes and increases workplace efficiency. For mobile setups and cordless drivers, the hex shank provides safer engagement under higher loads.

Material choice and geometry tuned for metalworking

Made from HSS‑G (high speed steel, ground), the bit offers a balance of hardness and toughness for drilling metals such as steel, cast iron, non‑ferrous metals and certain engineering plastics. The 118° Tip Angle favours easier penetration and better centring in softer metals like aluminium, while the overall bit geometry remains versatile for a wide range of workshop tasks. Note that fully ground HSS can be more brittle than rolled variants; therefore, recommended use is with adequate cooling and in appropriate drilling setups to maximise service life.

Practical use cases and handling recommendations

Experienced machinists and maintenance technicians will appreciate the combination of DIN 338 conformity and standardised lengths that support repeatable setups on both stationary and portable machines. For best results, use the correct cutting speed for the material and apply coolant when machining harder alloys. The bit is well suited to production tasks and repair work where precision and repeatability are required rather than rough or one‑off woodworking applications.

FAQ

What materials is the MetavCUT Twist Drill suitable for?
The MetavCUT Twist Drill, a precision Drill Bit made from HSS‑G, is intended primarily for metalworking and performs well in alloyed and unalloyed steels, cast iron, non‑ferrous metals and some hard plastics; for the hardest materials, follow recommended speeds and cooling practices.

How should the MetavCUT Twist Drill be clamped and operated for best life?
Clamping the MetavCUT Twist Drill in a properly sized chuck or a 1/4" bit holder for the Hexagonal Shank ensures secure torque transfer; use correct cutting speeds, steady feed and coolant as needed to reduce wear and avoid brittle failure.

What is a Twist Drill used for?
A Twist Drill is mainly applied when working on high‑strength materials and larger drill diameters; the ground flute geometry makes it easier to grind and yields precise holes that withstand higher loads.

Which three drill types are there?
The main drill types are Metal Drills, Wood Drills, and Stone/Concrete Drills.

Why are Twist Drills point‑sharpened?
Point‑sharpening reduces the chisel edge at the tip, significantly lowering friction and thus the required feed forces, while improving centring of the bit in the workpiece.

Can a Metal Drill be used in Wood?
A Metal Drill can be used in Wood, but it offers less guidance and a less clean finish compared with dedicated wood bits; however, such drills are easier to resharpen and have lower self‑feeding tendency.

For which drilling depths is the Twist Drill most commonly used?
A solid bore is typically executed 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.

Is HSS or HSSE better?
The common belief that HSSE is always superior to HSS is not universally true; decide based on your specific working conditions to determine whether the higher cost of HSSE is justified.
