Drill bit Art-Pol HSS spot-faced 14.5 mm for metal, model 53145

Art-Pol HSS spot-faced drill bit 14.5 mm is designed for metalworking applications where a flat seating or countersunk surface around a hole is required. Made from high-speed steel (HSS), this 14.5 mm diameter bit combines hardness and heat resistance to maintain cutting performance during repeated drilling operations in ferrous materials. The spot-faced geometry allows removal of raised material and produces a clean, even seat for fasteners or subsequent machining steps.

Advantages

The HSS construction provides wear resistance and thermal stability under higher cutting speeds typical of metal drilling. The spot-faced profile ensures consistent flatness around the hole and reduces the need for secondary finishing. This bit is compatible with common drilling equipment including hand drills and drill presses, offering reliable concentricity and straightforward chip evacuation when used with appropriate speeds and lubrication.

Suitable for (tasks / use cases)

• Creating flat seating or countersunk areas around holes in mild steel and other ferrous materials
• Preparing through holes and pilot holes before tapping or joining
• Spot-facing sheet metal and plate to ensure flush fastener installation
• General metal fabrication where precise seating surfaces are required

Key specifications

• Cutting material: high-speed steel (HSS)
• Nominal diameter: 14.5 mm
• Design: spot-faced / spotfacing geometry for flat seat creation
• Suitable material: mild steel, sheet metal and other ferrous metals
• Compatibility: usable with hand drills and drill presses

How to use

Secure the workpiece firmly to prevent movement and select a suitable drill chuck or arbor that accepts the bit shank. Use moderate spindle speeds and appropriate cutting fluid when drilling ferrous metals to reduce heat and improve chip evacuation. Start with a center punch or pilot hole if precise positioning is required. Apply steady, even feed pressure until the spot-face is achieved, then retract the bit periodically to clear chips.

Usage recommendations

For best results on thicker or harder ferrous materials, use cutting fluid and lower speeds to preserve bit life. Inspect the bit regularly for wear and replace when edge rounding or chipping is evident to maintain accurate, clean seat surfaces.
