Twist Drill — Short HSS-G, Ø 8.8 mm, 135°, Type N, Bright Finished, DIN 338

A short Twist Drill Type N for Drilling Machine use, designed for precise metal drilling in demanding industrial and workshop applications.

• Short design for higher drilling stability
• HSS-G ground geometry for clean, precise holes
• 135° tip for hard and stainless materials
• Fully ground shank for excellent concentricity
• Conforms to DIN 338 for reliable interchangeability

Faster, more reliable metal drilling for tough materials

The short HSS-G construction delivers a direct benefit: significantly reduced tendency to bend or whip during use, which translates into more precise holes and longer tool life under proper conditions. The 135° tip angle is optimised for harder metals and stainless steels, shortening the pilot time and improving centring on difficult surfaces. As a Type N normal-spiral geometry, this design balances chip evacuation and cutting action for typical metalworking tasks while allowing stable performance on stationary and mobile machines.

Stability and handling that improve machining results

A reduced overhang and the shortened overall length mean less vibration and better runout behaviour on the spindle; this yields cleaner hole edges and reduces rework. The fully ground shank guarantees improved concentricity in the chuck, so tolerances remain tight even during series production. With a diameter of 8.8 mm, a spiral length of 81 mm and an overall length of 125 mm, the tool is tailored for tasks where a compact, rigid drill bit is required to maintain accuracy in metals such as alloyed and unalloyed steels, cast steel and non-ferrous metals.

Who benefits and how to choose the right drill

Workshop professionals, toolmakers and maintenance technicians gain most from a short, ground HSS tool when precision and repeatability matter. The combination of HSS-G material and the short format reduces the required feed force and can increase drilling speed in appropriate conditions. For applications involving Sintereisen or Temperguss, the recommended approach is to use cutting fluid and moderate cutting parameters to exploit the drill’s performance without risking premature wear.

Understanding the key specifications and safe use

DIN 338 classifies short twist drills with cylindrical shank made from high-speed steel; in this case the designation indicates a ground geometry (HSS-G), produced by grinding rather than rolling. Ground drills typically achieve sharper cutting edges and higher runout precision, but they require careful handling because they can be more brittle than rolled variants. For best results, use appropriate coolant, clamp the tool securely, and keep overhangs minimal. These measures reduce heat and extend service life while ensuring consistent hole quality.

FAQ

What is the Twist Drill used for and which materials is it suited to?
The MetavCUT Twist Drill Type N is primarily used for metalworking; it is especially suitable for alloyed and unalloyed steel, cast steel, gusseisen and other hard materials. Its short, ground HSS construction provides improved stability and cleaner holes when used with appropriate machine settings and coolant.

How does the short format of this Twist Drill affect drilling performance?
A short design reduces the overhang and increases stiffness, which lowers vibration and improves concentricity. For the MetavCUT short Twist Drill this means better hole quality and the ability to operate at higher effective cutting speeds with lower feed force compared to longer equivalents.

For what is a Twist Drill mainly used?
A Twist Drill is mainly applied in the machining of high-strength workpieces and larger drill diameters. Its geometry is relatively easy to regrind and it withstands higher loads, making it suitable for demanding metalworking tasks.

Which three drill types exist?
The three primary drill categories are metal drills, wood drills and stone/concrete drills.

Why are Twist Drills pointed?
Pointing reduces the cross-edge at the tip of the Twist Drill, which significantly lowers friction and thus requires less feed force. At the same time the pointed geometry improves centring in the workpiece for more accurate drilling.

Can a Twist Drill be used to drill wood?
A metal Twist Drill such as the MetavCUT HSS-G can be used in wood, but it offers poorer guidance and a less clean finish than a dedicated wood drill. It is easier to resharpen and has less self-feeding tendency than specialised wood drills.

For which drilling depths is the Twist Drill the most used tool?
Solid drilling is commonly performed with Twist Drills. For diameters up to 20 mm and drilling depths up to 100 mm, the Twist Drill is the most frequently used tool.

What is better, HSS or HSSE?
The common assumption that HSSE steels are inherently superior to standard HSS is not universally correct. The decision should be based on the specific working conditions and whether the performance benefits justify the higher acquisition cost.
