Stanley Drill Bit Set, 13mm Maximum Size, 1mm Minimum Size - DT4957-QZ

This drill bit set is a 29-piece collection of twist drills intended for machining metal components in industrial and workshop settings. Manufactured from cobalt-alloyed high-speed steel, the set is designed for use with portable or bench-mounted drilling equipment when working with high-alloy steels and other demanding metallic materials.

Features & Benefits

• 5% cobalt HSS composition for elevated heat endurance and wear resistance
• Precision-ground DIN 338 geometry for accurate, centred starts
• Right-hand cutting helix to promote efficient chip evacuation
• Gold ferrous finish to reduce surface friction during drilling
• Extreme cobalt tip to minimise walking and improve first-cut accuracy

Applications

• Suitable for drilling stainless and chrome-nickel steels
• Ideal for machining heat- and acid-resistant steels
• Used for creating holes in cast-iron and bronze components
• Can be used on welded seams and high-strength alloys

What range of hole sizes does the set cover?

The kit spans metric diameters from 1mm up to 13mm, providing a wide selection for varied drilling tasks.

How does the tip design influence setup time?

The specialised tip reduces initial skidding, decreasing the need for centre-punching and shortening setup for repetitive operations.

Which drilling conditions suit these bits best?

They perform well at elevated cutting temperatures encountered when penetrating high-alloy steels, maintaining edge integrity under sustained loads.

How are chips handled during prolonged drilling?

The right-hand helix encourages consistent chip removal, lowering the risk of clogging in deep or continuous holes.
