Set of 3 HSS-TiN Step Drill Bits (5904012136106)

For the most demanding metalworking jobs, an HSS-TiN step drill bit can be indispensable. This power tool accessory is used for enlarging holes, centering drill holes, or milling interior edges. It can be operated with screwdrivers and drills equipped with cylindrical chuck jaws. The STALCO PERFECT HSS-TiN step drill bit is useful for demanding and professional tasks. It is made of HSS high-speed steel with a titanium nitride coating, providing high abrasion resistance and enabling work with the hardest metals. A spiral flute for debris removal and a cross-cut grind are formed during manufacturing. The drill bit's dimensions are laser-engraved, making it very comfortable to work with. Furthermore, it leaves a smooth edge inside the hole after drilling. The set includes three drill bits, which vary in diameter and pitch. All three drill bits are supplied in a durable plastic case for safe storage.
FEATURES AND ADVANTAGES
Ground, sharp edges speed up work and shorten the time needed to complete it.
Fast removal of spoil speeds up work and shortens the time needed to complete it.
Very long product life allows for significant cost reduction.
TiN coating significantly increases efficiency and work comfort.
All necessary sizes in one package ensure high work comfort.
FEATURES:

• Step drills for use in materials up to 4 mm thick FOR BURR-FREE DRILLING
• Ground handle with spiral flute enables optimal chip removal and reduces vibrations
• HSS [High Speed ​​Steel]
• High-alloy steel,
• mainly used for the production of cutting tools
• Laser-engraved dimensions
• Highest cutting smoothness thanks to axial and radial grinding
• Cross-ground tip allows for easy starting, drilling without the need for a center punch or pre-drilling
• Set of three step drills ranging from 4 to 30 mm Structural coating: TiN titanium nitride coating. ADVANTAGES OF STRUCTURAL COATINGS:
• optimal hardness to residual stress ratio, and thus high stability of the cutting edge geometry and uniform wear,
• higher thermal and chemical resistance enabling dry machining
• at higher speeds and reduced flute wear,
• better sliding properties resulting in better chip formation
• and higher quality of the machined surface,
• greater wear resistance, reducing tool costs
• maximum operating temperature approx. 600 nc

The HSS step drill is a strong, high-performance tool for burr-free drilling
and deburring of sheet metal, pipes and profiles, etc..
Step drills They have, as the name suggests, different steps that cut the desired diameter, and this is what distinguishes them from other types of drills.
They enable the economic production of holes of various diameters with a single tool.
