Metal drill bit set Smart HSS cylindrical 7.5 mm, 10 pcs (mpn 24-075)

Set of 10 Smart HSS cylindrical drill bits with a 7.5 mm cutting diameter designed for drilling metal. Each bit is made from high-speed steel (HSS) to maintain hardness and cutting performance at elevated temperatures. The cylindrical shank fits standard drill chucks and handheld drills, making the set suitable for workshop, maintenance and light industrial use where reliable metal drilling is required.

Advantages

The Smart HSS drill bits offer consistent cutting geometry and wear resistance typical of high-speed steel tools. Their 7.5 mm diameter provides a balance between material removal and hole accuracy for general metalworking. Cylindrical shanks ensure compatibility with a wide range of chucks and simplify bit changes. The set format of 10 pieces gives stock for repeated tasks and reduces downtime during production or repair work.

Suitable for

• Drilling holes in steel and other ferrous metals
• Working with non-ferrous metals such as aluminum and brass
• Maintenance, repair and workshop fabrication tasks
• Use in bench drills and handheld electric drills with compatible chucks

Key specifications

• Cutting material: high-speed steel (HSS)
• Shank type: cylindrical
• Cutting diameter: 7.5 mm
• Quantity in set: 10 pieces
• Typical applications: metal drilling, workshop and light industrial use

How to use

Select a drill chuck that securely clamps a cylindrical shank and install the 7.5 mm bit so that it is held straight and tight. Mark the drilling position on the workpiece, use a center punch for accurate starts on smooth surfaces, and set an appropriate drill speed for the metal type—lower speeds for harder steels, higher speeds for aluminium and soft alloys. Apply steady feed pressure without forcing the bit; use cutting fluid or lubricant when drilling steels to reduce heat and increase tool life. Withdraw the bit periodically to clear chips when drilling deeper holes.

Usage recommendations

For best results and longer tool life, match drill speed and feed to the metal being worked, use appropriate cutting fluid on ferrous materials, and ensure the drill chuck grips the cylindrical shank tightly. Inspect bits for wear or damage before use and replace worn drills to maintain hole quality and safety.
