Step drill bit HS STALCO PERFECT S-72532

For the most difficult metalworking tasks, the HSS-TiN step drill bit may be essential. This type of power tool accessory is used for enlarging holes, center punching the drilling point, or chamfering inner edges. The product can be operated with screwdrivers and drills equipped with chucks for cylindrical shanks. The STALCO PERFECT HSS-TiN step drill bit is useful for demanding and professional tasks. It is made of high-speed steel HSS with a titanium nitride coating. This provides high wear resistance and enables work with the hardest metals. During the manufacturing process, a spiral groove for chip evacuation and a cross grind on the tip were formed. The drill bit has laser-engraved dimensions, making work with it very convenient. Additionally, after drilling, it leaves smooth edges inside the hole. STALCO's offer includes three different drill bits, suitable for holes of various diameters and depths.

FEATURES AND BENEFITS Ground, sharp edges accelerate work and reduce the time needed to complete it. Fast chip evacuation accelerates work and reduces the time needed to complete it. Very long product service life allows for significant cost reduction. The TiN coating significantly increases efficiency and work comfort.

FEATURES:

Step drill bits for use in materials up to 4 mm thick FOR BURR-FREE DRILLING Ground shank spiral groove enables optimal chip evacuation and reduces vibrations High-speed steel HSS [High Speed Steel] high-alloy steel, mainly used for the production of cutting tools laser-engraved dimensions highest cutting smoothness thanks to axial grinding and radial relief cross grind of the tip enables easy start of work, drilling without the need for a center punch or pilot drillingStructural coating: TiN titanium nitride coating. ADVANTAGES OF STRUCTURAL COATINGS: optimal ratio of hardness to residual stress, and thus high blade geometry stability and even wear, higher thermal and chemical resistance enabling dry machining with higher speeds and reduced flute wear, better sliding properties resulting in better chip formation and higher quality of machined surface, greater wear resistance affecting the reduction of tool costs maximum working temperature approx. 600°C PRODUCT MATERIAL: HSS steel

PRODUCT APPLICATION: Drilling holes in steel, plastics, wood.

APPLICATION - MATERIAL -Sheet metal of ferrous and non-ferrous metals -Profiles and pipes -Copper, brass -Aluminum - use drill bits without structural coating -Stainless steel - use only HSS-E / HSS-Cobalt step drill bits -Plastics -Wall and roof sandwich panels

APPLICATION - INDUSTRY

• Electrical/electrical installation: drilling in panels and distribution cabinets for installing connectors
• Hydraulics, heating, air conditioning and ventilation: inspection holes, etc.
• Machining / manufacturing: various diameters and hole enlargement
• Automotive industry: holes for cable installations (mobile phones, antennas, wiring)
• Maintenance and repair work: various applications, e.g. hole enlargement

TECHNICAL DATA: Drill bit Ø 4-12 mm Step 1 mm Shank Ø 6 mm PROPERTIES The HSS step drill bit is a strong, high-performance tool for burr-free drilling and deburring of sheets, pipes and profiles, etc. Step drill bits have, as the name suggests, various steps that cut the desired diameter, and this is how they differ from other types of drill bits. They enable economical production of holes of various diameters with one tool.
