Drill bit Art-Pol HSS cylindrical 2.7 mm for metal, model 50527

The Art-Pol HSS cylindrical drill bit 2.7 mm for metal is a precision tool designed for drilling small-diameter holes in a range of ferrous and non-ferrous metals. Manufactured from high-speed steel (HSS), the bit provides a balance of wear resistance and heat tolerance that supports longer cutting life and consistent performance in light industrial, workshop and DIY environments. The cylindrical shank fits common chucks on hand drills and drill presses, enabling stable rotation and accurate hole placement.

Advantages

The HSS material offers improved hardness at elevated temperatures compared with standard carbon steels, reducing wear during repeated metal drilling. The 2.7 mm diameter is suitable for pilot holes, precision fastener locations and small-component fabrication where tight hole tolerances are required. The cylindrical shank design ensures compatibility with a wide range of drill chucks and provides straightforward mounting and removal.

Suitable for

• Drilling holes in steel, stainless steel and iron sheet metal
• Working with aluminum, brass and other non-ferrous metals
• Creating pilot holes for tapping and screw fastenings
• Small fabrication, maintenance and DIY metalworking tasks

Key specifications

• Cutting material: high-speed steel (HSS)
• Drill diameter: 2.7 mm
• Shank type: cylindrical shank for standard chucks
• Intended material: ferrous and non-ferrous metals
• Typical applications: precision drilling, pilot holes, small-component work

How to use

Secure the drill bit in a suitable drill chuck, ensuring it is seated straight and tightened to prevent wobble. Select a drilling speed appropriate for the metal being worked—lower speeds for harder steels, higher speeds for softer metals such as aluminum. Apply steady, even pressure and use cutting fluid or lubricant when drilling harder materials to reduce heat build-up and extend tool life. Withdraw the bit periodically on deeper holes to clear chips and avoid clogging.

Usage recommendations

Use appropriate personal protective equipment and clamp workpieces securely. For tapping operations, first drill the correct pilot hole size and use cutting oil to prolong bit life. Store the bit dry and clean to prevent corrosion and check periodically for wear or chipping; replace when cutting becomes inconsistent.
