IRWIN TURBOMAX PRO 15-Piece HSS Twist Drill Bit Set, 1.5–10 mm, DIN 338, Split Point, Metal/Wood/Plastic

For professionals who demand precision and longevity, the IRWIN TURBOMAX PRO 15-piece drill bit set delivers a complete range of diameters from 1.5 mm to 10 mm in a single, well-organized case. Unlike basic carbon steel bits that dull quickly or wander on contact, these fully ground HSS bits feature a 118° split point that bites instantly without a center punch, reducing walking and enabling clean, accurate holes in metal, wood, and plastic. Each bit is manufactured to DIN 338 standards, ensuring consistent length, flute geometry, and shank diameter for reliable performance in hand drills and drill presses alike.

Highlights

• 15-piece set covers 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 8, 9, and 10 mm diameters
• High-speed steel (HSS) with bright finish for heat resistance and corrosion protection
• 118° split point self-centers and reduces thrust pressure for faster starts
• Fully ground flutes for efficient chip evacuation and smoother cutting
• Straight cylindrical shank fits standard keyed or keyless chucks
• Durable plastic storage case with size markings for quick selection

In daily use

Whether you are drilling pilot holes for screws, enlarging existing openings, or working on thin sheet metal, the TURBOMAX PRO set keeps the right size within reach. The split point design eliminates the need for a center punch in most materials, while the right-hand cut and polished flutes reduce friction and heat buildup. The case snaps shut securely and stands upright, so the bits stay organized in a drawer or tool bag. From maintenance tasks to fabrication work, this set provides the versatility and durability expected from IRWIN.
