RUKO SPB Conjunto de 19 brocas helicoidais DIN 338 HSS revestidas a TiN, caixa metálica 1-10mm

Professional machinists and metalworkers rely on this 19-piece twist drill bit set for precise, efficient drilling in alloyed and unalloyed steel, cast iron, non-ferrous metals, and hard plastics. The set includes 19 bits in 0.5 mm increments from 1.0 mm to 10.0 mm, each ground from solid high-speed steel with a titanium nitride coating for reduced friction and extended life.

Key specifications

• Set contents: 19 twist drill bits
• Material: High-speed steel (HSS)
• Coating: Titanium nitride (TiN)
• Standard: DIN 338
• Shank type: Cylindrical
• Point angle: 135° split point
• Cutting direction: Right-hand
• Sizes included: 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, 5.0, 5.5, 6.0, 6.5, 7.0, 7.5, 8.0, 8.5, 9.0, 9.5, 10.0 mm
• Packaging: Robust metal cassette

Why choose it

The TiN coating reduces friction and heat buildup, enabling up to 40% faster drilling and six times longer life compared to uncoated HSS-R bits. The 135° split point self-centers and minimizes walking, making it ideal for accurate hole placement without a center punch.

Ideal use cases

• Drilling alloyed and unalloyed steel
• Cast steel and cast iron
• Sintered iron and non-ferrous metals
• Hard plastics
• Use with cordless drills, impact drills, and drill presses

Good to know

The bits are ground from solid metal for consistent quality and precision. The cylindrical shank fits standard drill chucks. The set comes in a robust metal cassette for organized storage and protection.
