  Bosch Professional Bosch HSS-AlTiN step drill bit set 4 - 12 / 4 - 20 / 6 - 30 mm 3 pcs. ( 2608588069 ) 3-face shank

  1 Review

  Sun, 12/14/2025

  Scope of Delivery: - 3x Bosch HSS-AlTiN step drill ( 4 - 12 / 4 - 20 / 6 - 30 mm ) Product Description: The Bosch HSS-AlTiN stepped drill bit enables quick and easy drilling of holes with different diameters. The cross-ground drill point makes it easier to start drilling, so no centre punching is required. The CNC-milled spiral flute optimally removes swarf and ensures low-vibration and therefore even drilling. The axial and radial relief grinding ensures maximum cutting performance and absolutely smooth results. The HSS steel is coated with AlTiN (aluminium titanium nitride), which guarantees a service life optimised for the use of coolant. The laser-marked diameter markings in both spiral flutes are permanent and easily recognisable. The 3-face shank enables a high torque and therefore fast and precise work. The Bosch HSS-AlTiN stepped drill bit is the perfect companion for anyone who wants to drill holes quickly and reliably. With its excellent performance and durable coating, it always offers optimum results. Technical Data: - Manufacturer: Bosch - Manufacturer designation: HSS-AlTiN step drill bit - Manufacturer number: 2608588069 - Design: HSS-AlTiN ( HSS steel with aluminium titanium nitride coating ) - Step diameter (range) mm: 4-12 / 4-20 / 6-30 - Shank diameter mm: 6.0 / 8.0 / 10.0 - Step height mm: 4 / 4 / 4 - Total length mm: 66.5 / 70.5 / 93.5 - For commercial use, please observe the building regulations!For commercial use, please observe the building regulations!

  EXACT Exact step drill set 3 pcs. 4 - 30 mm 1/4" ( 08014 ) HSS TIN spiral fluted

  Scope of Delivery: - 3x step drill ( 4 - 12 / 4 - 20 / 6 - 30 mm ) - 1x plastic cassette Product Description: With the 3-piece stepped drill bit set from EXACT, drilling with millimetre precision is no problem at all. With the step drills, which come in three different sizes (4 - 12; 4 - 20 and 6 - 30 mm), the drilling diameter can be determined with millimetre precision thanks to the laser scaling. A major advantage is the 1/4 inch bit shank, which allows the step drill to be used with any drill with a quick-release chuck. The HSS TIN drill bits have a titanium-nitride coating to achieve a longer service life and cutting speed, as well as good heat resistance. They therefore have a high tool quality and a long service life is guaranteed. These drill bits are therefore also suitable for materials with a tensile strength of less than 1000 N/mm². The step drill bit set is supplied in a high-quality plastic case, in which the drill bits are well organised and always ready to hand. Technical Data: - Manufacturer: EXACT - Manufacturer number: 08014 - Material: HSS TIN steel - Drill bit sizes: 4 - 12 / 4 - 20 / 6 - 30 mm - Shank: 1/4 inch bit shank - For commercial use, please observe the building regulations!For commercial use, please observe the building regulations!

  EXACT Exact step drill set 3 pcs. 4 - 30 mm ROTASTOP ( 07024 ) HSS TIALN spiral fluted

  Scope of Delivery: - 3x step drill ( 4 - 12 / 4 - 20 / 6 - 30 mm ) - 1x plastic cassette Product Description: With the 3-piece stepped drill bit set from EXACT, drilling with millimetre precision is no problem at all. With the step drills, which come in three different sizes (4 - 12; 4 - 20 and 6 - 30 mm), the drilling diameter can be determined with millimetre precision thanks to the laser scaling. A major advantage is the ROTASTOP shank, which prevents spinning in the drill chuck, ensures optimum torque transmission and guarantees easy tool changes. The HSS TIALN drill bits have a titanium-aluminium-nitride coating to achieve optimum tool life and maximum cutting speeds. This gives them outstanding tool quality and guarantees a very long service life. These drills are therefore suitable for alloyed steels with a tensile strength of up to 1200 N/mm². The step drill bit set is supplied in a high-quality plastic case, in which the drill bits are well organised and always ready to hand. Technical Data: - Manufacturer: EXACT - Manufacturer number: 07024 - Material: HSS TIALN steel - Drill bit sizes: 4 - 12 / 4 - 20 / 6 - 30 mm - Shank holder: ROTASTOP - For commercial use, please observe the building regulations!For commercial use, please observe the building regulations!
