Borenset Metabo 627156000 — HSS, TiN-gecoat, 19-delig

Drill bit set Metabo 627156000 — HSS, TiN coated, 19 pieces includes nineteen high-speed steel (HSS) bits with a titanium nitride (TiN) coating designed for metalworking and general workshop use. The set is intended to deliver improved wear resistance and extended tool life compared with uncoated HSS bits, providing consistent drilling performance across a range of common metals and engineering materials. Bits are suitable for use in hand-held and machine drills where standard twist HSS bits are required.

Advantages

The TiN coating reduces friction and increases hardness at the cutting edge, which helps to maintain sharpness longer and reduce the frequency of bit replacements. HSS substrate offers toughness and heat resistance appropriate for drilling through steels and non-ferrous metals. The 19-piece assortment covers a range of commonly used diameters so users can select the appropriate size for precision holes without needing individual purchases. The set balances durability and cost-effectiveness for both professional and DIY tasks.

Suitable for

• Drilling holes in mild and alloy steels
• Work on aluminium and other non-ferrous metals
• General workshop and maintenance tasks
• Use with hand-held electric drills and drill presses

Key specifications

• Material: High-speed steel (HSS)
• Coating: Titanium nitride (TiN)
• Quantity: 19 pieces
• Design: Standard straight-shank twist drill geometry
• Intended use: Metalworking and general workshop drilling

How to use

Select the drill bit size that matches the required hole diameter and secure the bit in the chuck of a hand-held drill or drill press. Use appropriate cutting speeds and feed rates for the material being drilled—lower speeds for harder steels, higher speeds for softer non-ferrous metals. Apply cutting fluid or lubricant when drilling steels to reduce heat buildup and improve chip evacuation. Maintain steady pressure and allow the bit to cut; avoid excessive force that can cause bit breakage or accelerated wear.

Recommendations

Inspect bits before each use for signs of wear or damage. Re-sharpen or replace bits when cutting performance declines. Store the set in a protective case or holder to prevent corrosion and protect the TiN coating from abrasion. When drilling stainless steels or other very hard alloys, consider using specialized cobalt or carbide grades as required.
