Metric Drill Bit Set AB Tools HSS Split 51pc 1-6mm 0.1mm Increment

Description

Product Overview

The AB Tools 51‑piece metric drill bit set is engineered for precision and durability, delivering high‑speed steel (HSS) split‑point drills that cover diameters from 1 mm to 6 mm in exact 0.1 mm increments. Each bit features a gold‑oxide finish that significantly enhances wear resistance, extending tool life even under demanding industrial conditions. The 135 degree split‑point design minimizes walking, allowing users to start holes accurately on both metal and plastic substrates. This set is packaged in a compact, sturdy case measuring 6.69 × 4.72 × 1.97 inches, making storage and transport straightforward for professionals who move between job sites.

Beyond the core specifications, the set includes a straight shank that fits standard 3/8‑inch and 1/2‑inch chucks, ensuring compatibility with a wide range of drill presses and hand‑held drills. The spiral flute design efficiently evacuates chips, reducing heat buildup and preserving the cutting edge. With a total weight of 1.4 pounds, the collection balances heft for stability with enough lightness for extended use without fatigue. The product’s global trade identification number (GTIN‑14) is 05056663614196, confirming its authenticity and traceability within the supply chain.

Usage

Designed for versatility, this metric drill bit set excels in metalworking, electronics assembly, plastic fabrication, and general maintenance tasks. The fine 0.1 mm step increments enable users to select the exact diameter required for tight tolerances, making the set ideal for aerospace component drilling, automotive repair, and precision instrument manufacturing. Whether you are creating pilot holes for screws, enlarging existing openings, or performing detailed prototyping, the split‑point geometry ensures clean entry and reduces the need for secondary reaming.

The set is equally suitable for hobbyists and DIY enthusiasts who demand professional‑grade performance without the expense of multiple single‑bit purchases. Its gold‑oxide coating protects against corrosion, allowing storage in humid workshops without degradation. The bits perform reliably on stainless steel, aluminum, brass, and high‑impact plastics, providing a single solution for mixed‑material projects. Users appreciate the ergonomic feel of the straight shank, which offers a secure grip in both corded and cordless drill systems.
