Karosseriebohrer (Body Drill) — Twist Drill, 4 mm, 135°, Double-sided, Bright Finished, Fully Ground, HSS-G

A Karosseriebohrer (Body Drill) designed as a double-sided Twist Drill for precise metalworking with a 4 mm diameter and a 135° point angle, suitable for hand Drilling Machines and industrial use

• MetavCUT Body Drill for metal applications
• 4 mm Diameter for accurate pilot holes
• 135° Point Angle for harder materials
• Double-sided design offers two usable tips
• Fully ground HSS-G for clean, precise holes

Durable HSS-G construction for demanding metalwork

The fully ground HSS-G material ensures a sharp cutting geometry and high roundness accuracy, which produces clean holes in a wide range of metals. Because the flutes are produced by CNC grinding rather than by rolling, the bit achieves very precise cutting edges that reduce burr formation and improve hole quality. This design is particularly advantageous when working with legierte and unlegierte Stahl, Gussstahl and other hardened materials where a stable, sharp tip matters for consistent results.

Faster drilling with lower force and reliable centring

Thanks to the double-sided design and the ground geometry, this Twist Drill requires noticeably less feed force and delivers accelerated penetration compared with conventional bits. The reduced thrust demand and the optimized point geometry mean that drilling can be performed up to 40 % faster while needing less operator pressure, making repetitive tasks easier and reducing operator fatigue. The 135° point angle improves centring and performance in harder materials while lowering the risk of walking on the workpiece.

Practical design for metalworking workshops and on-site jobs

The short, robust shape of this double-ended twist drill makes it ideal for bodywork, sheet-metal and rivet-hole preparation where stability and repeatable hole quality are essential. The bright finished surface improves visibility of the cutting edges, and the fully ground shaft provides excellent runout and seating in chucks. Compatibility with standard hand Drilling Machines means this bit is versatile for both stationary and portable setups, offering dependable results across workshop and field applications.

Who benefits from this Body Drill and how to use it effectively

Craftspeople, maintenance technicians and metal fabricators will appreciate the combination of precision and practical durability. When machining cast parts, tempered steels or high-strength alloys, using coolant and a steady drill speed suited to the material will extend tool life. The double-ended Twist Drill can be reversed once one tip is dulled, effectively giving two usable cutting tips per tool and improving cost efficiency for repetitive drilling tasks.

FAQ

What are Twist Drills used for?
Twist Drills like the MetavCUT Karosseriebohrer (Body Drill) are primarily used for machining high-strength materials and larger drill diameters; their shape allows straightforward sharpening and they withstand greater loads, making them suitable for tasks such as creating holes in sheet metal and structural components.

Which three drill types exist?
Commonly distinguished drill types are metal drill, wood drill and stone/concrete drill; the MetavCUT Karosseriebohrer is designed as a metal drill (Twist Drill) optimised for steel and non-ferrous metals.

Why are Twist Drills re-sharpened at the tip?
Re-sharpening reduces the cross cutting edge at the tip, which lowers friction and the feed forces required; this results in better centring of the MetavCUT Karosseriebohrer and improved drilling performance in demanding materials.

Can a metal Twist Drill be used in wood?
A metal drill such as the MetavCUT Karosseriebohrer can be used in wood, but guidance is reduced and finish quality may be lower; however, these bits are easier to re-sharpen and exhibit less self-feeding compared with specialised wood bits.
