Conjunto de brocas helicoidais HSS para metal 1-10 mm, 19 peças, DIN 338, haste cilíndrica, ângulo de ponta 118°, retificadas, caixa de plástico

Every metalworker, maintenance technician, or serious DIYer knows the frustration of dull bits that wander and burn. This 19-piece HSS twist drill bit set in a compact plastic case solves that with a full diameter range from 1.0 mm to 10.0 mm in 0.5 mm increments, so you always have the right size for precise pilot holes, clean through-holes, or deburring in steel, aluminium, wood, and plastics. The bits are manufactured to DIN 338 with ground flutes and a bright finish for smooth chip evacuation and reduced friction. Use them in corded drills, cordless drills, or drill presses for consistent, accurate results.

Why choose it

Ground flutes and a precise 118° point angle mean these bits cut rather than scrape, reducing heat build-up and extending bit life. The bright finish helps prevent corrosion and keeps the flutes clear. With a full set from 1 mm to 10 mm, you eliminate guesswork and stop buying singles. The sturdy plastic case keeps everything organised and protected, so you can grab the right bit in seconds.

Ideal use cases

• Drilling steel, stainless steel, aluminium, and other metals
• Creating pilot holes for screws in wood and plastic
• General workshop, automotive, and maintenance tasks
• Use with corded drills, cordless drills, or drill presses

Good to know

For best results, use cutting fluid when drilling hard metals, and reduce speed as diameter increases. The h8 tolerance ensures consistent hole sizing for dowels, taps, or clearance fits. Store bits in the included case to prevent chipping and keep them sharp.
