HSS Drill Bit (reduced shank 13mm) 21.00 mm
HSS Drill Bit (reduced shank 13mm) 21.00 mm
Almost every do-it-yourselfer has worked with them at one time or another: the classic drilling tools for cordless screwdrivers, drills, impact drills or hammer drills. twist drill bit consist of the drill shank, chip-removing grooves and the drill point. Decisive for the application of the drill is not only the material, but also the cutting edge geometry, the rake angle and the spiral angle, the so-called twist.
At BAER you get HSSR- twist drill bit in proven BAER-industrial quality at an unbeatable price-performance ratio. The twist drill bit are available in many dimensions. Especially when it comes to tools, it is always worth investing one or two euros more. See for yourself.

Metal drill DIN 338, right-hand cutting with taper cone grinding
roll-rolled, high-speed steel (HSS steel)
The material HSS "High Speed Steel" is suitable for general drilling tasks. They replace drills made of conventional tool steel because they have better properties, such as up to four times higher cutting speed.
The HSSR- twist drill bit according to DIN 338 are roll-rolled and have a vaporised surface. The cutting direction is right and the point angle is 118°.
They are suitable for drilling steel and cast steel (alloyed and unalloyed), grey cast iron, malleable cast iron, nodular cast iron, sintered iron, nickel silver, graphite, bronze, brass and aluminium .
BAER HSSR twist drill bit with reduced shank
The design with reduced shank makes it possible to use drills that have a larger diameter than the matching drill chuck. This makes the BAER HSSR twist drill bit suitable for all common hand drills. Please make sure that the drill bit is firmly seated in the drill chuck. The torques to be transmitted should not be underestimated. Pre-drilling may be advisable.
Quality for a long service life
The high-alloy tool steel HSS can work with up to four times higher cutting speeds than ordinary tool steel. Roll-rolled twist drill bit have good chip evacuation and high breaking strength.
Our HSSR twist drill bit are characterised by:
- high breaking strength
- good chip evacuation
- Wear resistance
- Cutting edge stability
This means that BAER HSSR twist drill bit made of high-speed steel HSS can also cope with many material requirements. Precise work and long-term cost savings are added to this.
