Drill bit set FANAR WIERTLA NWKA ø 1.00–10.00 mm 19 pcs HSSE TiN INOX

FANAR WIERTLA NWKA ø 1.00–10.00 mm 19 pcs HSSE TiN INOX is a precision drill bit set designed for drilling stainless steel and other metals. The set includes 19 twist drills with diameters from 1.00 mm up to 10.00 mm in standard increments, manufactured from HSSE (high-speed steel with cobalt) for increased hardness and heat resistance. Each bit is coated with titanium nitride (TiN) to improve wear resistance and cutting life when used in workshop, industrial and maintenance applications that demand accurate, repeatable holes.

Advantages

The HSSE substrate provides improved toughness and thermal stability compared with standard high-speed steel, reducing risk of chipping when drilling harder alloys. TiN coating decreases friction and extends tool life, enabling higher cutting speeds and fewer tool changes. The set’s wide diameter range from 1.00 mm to 10.00 mm covers common small to medium hole sizes, making it practical for precision tasks. The drills are suitable for use in handheld drilling and machine setups when correct speeds and feeds are observed.

Suitable for

• Drilling stainless steel (INOX) and corrosion-resistant alloys
• General metalworking: mild steel, alloy steel, and non-ferrous metals
• Workshop repairs, maintenance and fabrication tasks
• Precision hole making in jigs, fixtures and metal components
• Bench and machine drilling where a range of diameters is required

Key specifications

• Material: HSSE (high-speed steel with cobalt)
• Coating: Titanium Nitride (TiN) for reduced wear
• Diameter range: 1.00 mm to 10.00 mm, 19 pieces covering standard increments
• Type: Twist drill bits (spiral flute geometry)
• Intended materials: Stainless steel (INOX) and various metals

How to use

Select the appropriate diameter for the hole required and secure the workpiece to prevent movement. Use a suitable drill chuck to clamp the bit with correct runout and alignment. For stainless steel and other hard alloys, use moderate spindle speeds and steady feed to avoid work hardening; apply cutting fluid or coolant to reduce heat and flush chips. Maintain consistent pressure without forcing the drill; withdraw occasionally to clear chips and allow cooling. Inspect bits for wear and replace when the cutting edges become rounded or damaged.

Usage recommendations

For best results when drilling stainless steel, start with lower RPMs and increase speed only if the bit remains cool and cutting smoothly. Use cutting fluid to prolong TiN coating life and improve chip evacuation. Store the set in a dry place and avoid impacts to preserve tip geometry.
