Drill bit Art-Pol HSS 14 mm — AR50140, high-speed steel twist drill

The Art-Pol HSS 14 mm twist drill AR50140 is a high-speed steel cutting tool designed for general-purpose drilling in metal and other common workshop materials. With a straight shank and single-piece construction, this 14 mm diameter drill bit is intended for use in hand-held drills and drill presses, offering a balance of toughness and cutting performance for manufacturing, maintenance and DIY applications.

Advantages

The high-speed steel composition provides good wear resistance and heat tolerance during continuous drilling operations. The single-piece, straight-shank design ensures stable seating in chucks and reduces runout when used in both portable drills and bench units. The 14 mm diameter delivers a precise hole size for fastening, clearance and preparatory operations while remaining compatible with commonly available drill holders.

Suitable for

• Drilling holes in mild and alloy steels
• General metal fabrication and maintenance work
• Workshop and DIY projects requiring a 14 mm hole
• Use with hand drills and drill presses

Key specifications

• Material: high-speed steel (HSS)
• Diameter: 14 mm
• Shank type: straight shank, single-piece construction
• Tip style: twist drill geometry suitable for metalworking
• Typical applications: metal, some plastics and general-purpose workshop materials

How to use

Secure the drill bit in the drill chuck so the shank is fully seated and tightened to minimize runout. Select an appropriate spindle speed and feed rate for the material being drilled—slower speeds for hard metals and higher speeds for softer materials. Use cutting fluid or coolant when drilling metals to reduce heat build-up and prolong tool life. Drill with steady, moderate pressure and clear chips from the hole periodically to maintain cutting efficiency and avoid clogging.

Usage recommendations

For best results in steel, pre-mark and center-punch the drilling location, start with a pilot hole if necessary, and apply cutting fluid. Inspect the cutting edge for wear and replace the bit when performance degrades to maintain hole accuracy and surface finish.
