Twist Drill — Extra Long Drill Bit (7 mm, 135°) HSS‑G, Bright Finished, DIN 1869 — MetavCUT

A Twist Drill extra long HSS‑G drill bit for Drilling Machines, designed for deep metal drilling and precise holemaking.

• 7 mm diameter for precision metalwork
• Extra long design for deep bore applications
• Fully ground shank for high concentricity
• HSS‑G material for hard metals and longevity
• 135° tip angle reduces walking in tough materials

Faster deep drilling thanks to extra long design

The extra long overall length delivers the reach required for deep drilling tasks without the need to reposition workpieces, making the bit ideal for access-restricted setups. Made from HSS‑G, this Twist Drill combines hardness with a ground geometry that produces clean, precise holes in steel and cast materials; the CNC grinding process yields sharp cutting edges and high runout accuracy, which shortens machining time and improves repeatability.

Reliable penetration in hard materials with 135° tip

A 135° tip angle provides a more gradual cutting action suited to harder alloys and stainless steels, lowering the risk of chipping at the entry and improving centering when starting a hole. This geometry reduces the need for pilot operations in many cases and helps maintain edge life under elevated contact stresses, so fewer tool changes are necessary during a job.

Clean chips and better cooling for extended tool life

The deep spiral flute (spiral length 200 mm) evacuates swarf efficiently from deep bores, while the bright finished surface supports smoother chip flow and easier cleaning. When used with appropriate coolant and a stable setup on a Drilling Machine, the combination of flute geometry and fully ground shank minimizes heat build-up and supports longer service intervals for the cutting edge.

Precise guidance and handling in production environments

The fully ground shank (fully ground) ensures excellent concentricity and stable clamping, reducing vibration and improving surface quality of the bore. Consciously engineered to DIN 1869 tolerances, this Twist Drill is suited for workshop and production use where consistent hole quality and interchangeability are required.

Who benefits from this drill and how to use it

Designed primarily for machining professionals and maintenance technicians working with legierter and unlegierter steels, cast iron and non‑ferrous metals, this bit excels where deep, accurate holes are required. For best results, secure the workpiece, use a stable Drill Machine setting, apply suitable coolant, and avoid excessive feed to prevent brittle fracture typical of ground HSS tools.

FAQ

What is the Twist Drill by MetavCUT best used for?
The MetavCUT Twist Drill is primarily used for machining high‑strength materials and larger drill diameters; its extra long configuration and HSS‑G grade make it well suited for deep holes in legierte and unlegierter steel, cast iron and hard plastics, providing clean, precise bores under demanding conditions.

Can the MetavCUT Twist Drill be used with a regular drilling machine?
Yes, this MetavCUT Twist Drill is designed for use in a Drilling Machine; for optimal performance secure the bit in a precise chuck, apply appropriate coolant and moderate feed rates to exploit the ground geometry and avoid undue stress on the cutting edge.

What are Twist Drills used for?
Twist Drills are mainly applied to the machining of high‑strength materials and larger drill diameters; their shape makes them easy to sharpen and capable of withstanding significant loads.

Which three drill types exist?
There are three common categories: metal drills, wood drills and masonry/concrete drills.

Why are Twist Drills sharpened?
Sharpening reduces the cross‑cut at the tip, lowering friction and thus the required feed forces; it also improves centring at the start of the hole, giving better guidance and less wander.

Can metal Twist Drills be used to drill wood?
Metal Twist Drills can be used in wood, but they generally offer less guidance and a less clean finish than dedicated wood drills; however, they are easier to resharpen and exhibit less self‑feeding tendency.

At what drilling depths are Twist Drills most commonly used?
Twist Drills are the go‑to tool for through drilling in solid materials; they are most frequently used for diameters up to about 20 mm and depths up to around 100 mm.

Is HSS or HSSE better?
The common assumption that HSSE is categorically superior to HSS is not universally true; when choosing, assess whether your working conditions justify the higher cost of HSSE for improved wear resistance in specific applications.
