VGPUN1T Unibit 1/8 to 1/2 Inch - Unibit

The Unibit VGPUN1T 1T Step Drill Bit is a professional-grade solution engineered for demanding automotive and industrial applications. This versatile tool consolidates 13 common hole sizes, ranging from 1/8" to 1/2", into a single durable bit, streamlining operations and reducing the need for multiple individual drill bits. Constructed from high-speed steel with a Titanium Nitride (TiN) coating, it delivers precise, clean holes and withstands the rigors of demanding workshop environments.

Key Features

• SpeedPoint Tip: Facilitates faster penetration and prevents bit walking, eliminating the need for center punching and ensuring accurate starts, even on curved surfaces.
• Multi-Step Design: Offers 13 distinct hole sizes, ranging from 1/8" to 1/2" in 1/32" increments, effectively replacing numerous individual drill bits and enhancing efficiency.
• Single-Fluted Cutting Edge: Engineered to produce consistently true, round holes and provide greater control throughout the drilling process, particularly in sheet metal.
• Industrial-Grade Durability: Made from hardened high-speed steel with a Titanium Nitride (TiN) coating, this bit resists heat and friction, significantly extending cutting edge life for maximum resilience in professional use.
• 3-Flatted Shank: Designed to prevent slippage in the drill chuck, ensuring secure fastening and stable operation during high-torque applications.

Applications

The Unibit 1T is ideal for creating precise holes in various thin materials up to 1/8 inch thick, including stainless steel, copper, brass, aluminum, plastic, and laminates. It is an indispensable tool for automotive bodywork, electrical installations, HVAC system fabrication, chassis modifications, and general metalworking tasks where clean, accurately sized holes are critical for proper fit and finish. This step drill bit also works well for enlarging existing holes in panels and covers.
