HARFINGTON 3/32″ Hex Shank Drill Bits 1/4″ Twist Set 76mm M35 HSS

Description

Product Overview

HARFINGTON brings a precision‑engineered set of 3/32″ hex‑shank drill bits designed for demanding applications across wood, metal, plastic, and alloy materials. Each bit measures 76 mm in total length, with a 24 mm cutting length and a robust 1/4″ (6 mm) hex shank that fits securely into standard power drills. The core of the bit is made from M35 cobalt high‑speed steel, a premium alloy known for its superior hardness and heat resistance. A titanium coating envelops the cutting edge, providing an extra layer of wear resistance that prolongs service life and maintains sharpness even under heavy use. The fully ground spiral groove design efficiently evacuates chips, reducing friction and heat buildup, while the 135° split‑point geometry initiates drilling with minimal walking, delivering clean, accurate holes on the first pass.

Usage

These hex‑shank bits are ideal for a wide range of DIY projects and professional tasks. Whether you are assembling furniture, installing electrical fixtures, fabricating metal brackets, or crafting custom plastic components, the bits provide reliable performance. The 1/4″ hex shank allows for quick bit changes without the need for additional adapters, making them perfect for fast‑paced work environments. Use them with cordless drills, impact drivers, or bench‑mounted drill presses to achieve consistent results. The bits excel in drilling into stainless steel, copper, aluminum, zinc alloy, cast iron, hardwood, softwood, and engineering plastics, offering versatility that meets the needs of hobbyists, contractors, and maintenance technicians alike.

FAQ

What materials can these drill bits handle?

The bits are engineered to drill through a broad spectrum of materials, including stainless steel, copper, aluminum, zinc alloy, cast iron, hardwood, softwood, and engineering plastics.

Do I need a special adapter for the 1/4″ hex shank?

No additional adapter is required. The 1/4″ hex shank fits directly into standard drill chucks that accept 1/4″ hex accessories, allowing for quick and secure bit changes.

How do I maximize the lifespan of the titanium coating?

Use moderate drilling speeds, apply cutting fluid when drilling metal, and avoid excessive pressure. Allow the bit to cool between passes, especially when working with hard alloys.

Are these bits compatible with impact drivers?

Yes, the robust hex shank is designed to handle the torque from impact drivers, but for the longest life, use them at lower impact settings when drilling metal.
