HSSE Core Hole Extreme Drill Bit Set M 3 - M 12
HSSE Core Hole Extreme Drill Bit Set M 3 - M 12
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 can get ground HSSG- twist drill bit in proven BAER-industrial quality for all common materials used for drilling. The drills are therefore designed to achieve an optimum ratio between performance and price. The drills are suitable for steel, cast steel, grey cast iron, malleable cast iron, nodular cast iron, sintered iron, nickel silver and graphite and are also suitable for precise and fast work due to the ground drill point.
The professional HSSE drill bit set from BAER contains all drill bit sizes to pre-drill core holes for M 3 - M 12 threads, so you always have the right drill bit to hand.
ATTENTION:
Do not drill into pre-drilled holes! (The cutting edges of the drills wear out more quickly and unevenly and can break as a result) Always drill only into the full material at the appropriate speed.

Extreme drill bit DIN 338, right-hand cutting with cylindrical shank
ground from the solid, HSSE/co-steel, with X-TRA split point
Our twist drill bit are mainly used in industrial production. Among other things, they can be used in CNC machines, pillar drills, drill presses, cordless screwdrivers, impact drills and hammer drills. With their cylindrical shank, they can be clamped in both quick-change drill chuck and keyed drill chuck. The drills have a split point and the point angle is 135°.
As they are characterised by high efficiency and low production costs, they are often used in series production
Universal drills for every application
Every material has its own individual machining behaviour. That is why twist drill bit must have the right geometries and be made of high-quality materials. Twist drill bit consists of the drill shank, the chip-removing flutes and the drill point. Decisive for the application range of the drill is not only the material, but also the cutting edge geometry, the rake angle and the helix angle, the so-called twist. This is the only way to ensure a good chip transport and a dimensionally accurate hole. The extreme twist drill bit is ideal for drilling iron, steel and bronze up to 1300 N/mm² as well as high-strength CrNi-based alloys, rust-, acid- and heat-resistant steels. Of course, you can also drill in wood or aluminium.
Quality for a long service life
The high-alloy tool steel allows up to four times higher cutting speeds than conventional tool steel. Due to the cobalt alloy (5%), the material is more heat-resistant and has a higher hardness than HSSG drills. It retains its hardness up to approx. 600-650 °C.
Our twist drill bit are characterised by:
- Temperature resistance / hardness
- close tolerances
- Self-centering
- Wear resistance
- Cutting edge stability
- high smooth running
- good chip removal
This means that BAER twist drill bit can cope with many material requirements. Precise work and long-term cost savings are added to this.
