Twist Drill — HSS‑G extra long Twist Drill, 7.5 mm, 135° tip, bright finished, fully ground shank, DIN 1869

The Twist Drill extra long HSS‑G is a specialist drill for Drilling Machine applications, engineered for deep and demanding metal drilling tasks.

• Extra long design for deep hole access
• 135° tip for harder materials and quick entry
• HSS‑G ground geometry for precise, clean holes
• Fully ground shank for high concentricity
• Suited for drilling in alloyed and unalloyed steels

Deep drilling reach for confined or deep workpieces

The Extra Long configuration and an overall length of 225 mm combined with a spiral length of 155 mm allow access to deep or hard‑to‑reach drill positions, so fewer tool changes are required. This design makes it easier to create long, straight holes in components where standard lengths fall short. For users who need extended reach during maintenance, workshop or production drilling, the extended geometry increases flexibility without sacrificing control.

Faster cutting with ground HSS‑G geometry and reduced feed forces

The HSS‑G material and CNC ground flutes deliver sharp cutting edges and excellent roundness, which translate into up to 40% faster drilling and roughly 50% lower feed force compared with conventional HSS types under comparable conditions. This benefit reduces operator effort and can improve cycle times in repetitive machining tasks. The ground construction also produces cleaner chips and more accurate hole diameters, which is especially advantageous for subsequent reaming or finishing operations.

Optimised for harder metals and machine use

A 135° tip angle is selected to perform reliably in harder materials such as stainless steels and tempered steels; the larger tip angle shortens the initial plunge time and improves centring on difficult surfaces. The MetavCUT Twist Drill is specified to meet DIN 1869 and is particularly recommended for use in Drilling Machines with adequate cooling. As the ground variant can be more brittle than rolled types, machine mounting and coolant are advised to maximise tool life and avoid breakage under heavy loads.

Clear benefits for workshops, maintenance and production

Customers in metalworking, toolrooms and industrial maintenance gain from consistent hole quality and reduced rework. The combination of bright finished surface and fully ground shank improves clamping stability and runout, which benefits hole accuracy and tool longevity. For users requiring reliable deep-hole machining with predictable results, this HSS‑G Twist Drill by MetavCUT offers a balance of precision and reach while conforming to recognised standards.

FAQ

What is the MetavCUT Twist Drill used for and where does it perform best?
The MetavCUT Twist Drill is primarily used for drilling metal and is optimised for deep holes and tougher materials; it performs best in machine applications such as Drilling Machines where the extra length and HSS‑G ground geometry enable precise, deep bore creation in alloyed and unalloyed steels, cast materials and hard plastics.

Which three drill types exist?
The main categories are Metal Drills, Wood Drills and Stone/Concrete Drills; the MetavCUT Twist Drill belongs to the Metal Drills group and is designed for metalworking tasks.

Why are Twist Drills point‑ground?
The point grinding reduces the cross‑cut at the tip, lowering friction and therefore requiring less feed force; this improves centring in the workpiece and reduces the risk of wandering, which is a key reason the MetavCUT Twist Drill is ground for high‑precision metal drilling.

Can a metal drill be used for wood?
A Metal Drill such as the MetavCUT Twist Drill can be used in wood, but guidance and finish are usually inferior compared with purpose‑made wood drills; metal drills are easier to resharpen and have less aggressive self‑feed, so results can be acceptable for non‑critical wooden jobs.

At which depths is the Twist Drill most commonly used?
For solid drilling, Twist Drills are typical up to diameters of about 20 mm and depths up to 100 mm; the MetavCUT Extra Long variant is intended for deeper or harder‑to‑access hole requirements where standard lengths would be insufficient.

What is better, HSS or HSSE?
There is no universal rule that HSSE is always superior to HSS; the choice depends on working conditions, material and cost considerations. Evaluate whether the specific machining demands justify the higher investment in HSSE for your application.
