Twist Drill (Type N) — 6.3 mm, 135° Tip, Short, 5% Cobalt‑Alloyed, HSS‑E, DIN 338

The Twist Drill Type N is a short HSS‑E drill designed for precise metal drilling with hand and drilling machines, offering high stability and wear resistance in demanding machining tasks.

• Short design for improved stability and precision
• 5% Cobalt‑alloyed HSS‑E for increased heat resistance
• 135° Tip angle for harder materials and stainless steel
• Fully ground shank for excellent runout accuracy
• Conforms to DIN 338 for standardised short twist drills

Exceptional Stability and Accurate Hole Making for Metalworking

Short Spiral Geometry delivers a measurable benefit in everyday machining: the reduced overhang increases Stability and cuts down on bit deflection, so holes come out truer to size. This Short Twist Drill with a 63 mm Spiral Length and 101 mm Overall Length is particularly suited to operations where rigidity matters, such as drilling in steel or when using a Hand Drilling Machine. The 135° Tip shortens initial entry time in harder materials and helps maintain centring under load.

Enhanced Material Properties for Longer Life under Heat and Load

Manufactured from HSS‑E with 5% Cobalt, this Twist Drill offers greater red hardness and wear resistance compared with conventional HSS. The cobalt‑alloyed composition means the tool tolerates higher cutting temperatures and preserves cutting edges longer when machining alloyed and unalloyed steel, cast iron and non‑ferrous metals. HSS‑E (High Speed Steel with Cobalt) describes a faster heat‑resistant steel grade that balances toughness with hardness, reducing the need for frequent tool changes.

Precision Grinding and Standard Compliance for Reliable Results

The fully ground flute geometry produces very sharp cutting edges and high concentricity, yielding clean, accurate bores in metal. As defined by DIN 338, this Short Twist Drill is produced to standardised dimensions and tolerances for short drills with cylindrical shanks. Ground tools typically give better hole quality than roll‑formed alternatives; they are easier to resharpen but require proper cooling and appropriate speeds to avoid premature breakage.

Optimised for Metal Applications and Practical Use Recommendations

Designed as a classic Type N normal‑spiral metal drill, this tool is recommended for a range of metalworking tasks on both stationary and portable drilling equipment. The shorter cutting length reduces the risk of bending and is therefore ideal for precision holes and tougher materials. For best results, use suitable cutting speeds, adequate lubrication or coolant when drilling stainless or hardened steels, and secure the workpiece to minimise vibration. The construction allows for easier regrinding when required, extending service life.

FAQ

What is the best use for the MetavCUT Twist Drill Type N?
The MetavCUT Twist Drill Type N is primarily used for machining high‑strength materials and larger drill diameters; its short design and HSS‑E composition make it easier to resharpen and capable of withstanding higher loads during metalworking.

Which three drill types are commonly distinguished?
In general practice the main categories are Metal drills, Wood drills and Stone/Concrete drills; the MetavCUT Twist Drill belongs to the metal drill category and is optimised for steel and similar materials.

Why are Twist Drills sharpened at the point?
The point sharpening reduces the cross‑cut at the tip of the Twist Drill, lowering friction and therefore the required feed forces; additionally, a properly sharpened tip improves centring in the workpiece.

Can a metal Twist Drill be used to drill wood?
A metal drill such as the MetavCUT Twist Drill can be used in wood, but guidance and finish are typically inferior compared with dedicated wood drills; metal drills are easier to resharpen and exhibit less self‑feeding in soft materials.

For which drilling depths is the Twist Drill most commonly used?
A through hole in solid material is often executed with a Twist Drill; for diameters up to about 20 mm and drilling depths up to approximately 100 mm the Twist Drill is the most frequently used tool.
