Product Overview

The YONK HSS Twist Drill Bit Set is an essential tool for professional contractors, DIY enthusiasts and home users, designed for precise, efficient drilling in a wide range of materials.

Key Features

Premium HSS & Titanium Coating

Each drill bit is crafted from high-grade High Speed Steel (HSS), which offers exceptional hardness, heat resistance and wear resistance, ensuring long service life even under heavy-duty use. The titanium coating further enhances hardness, reduces friction and extends the bit's lifespan, making it ideal for drilling in hard metals like steel, aluminum, as well as wood, plastic and other common materials.

Precision Twist Design

The optimized spiral flute design ensures smooth chip removal, prevents clogging, and delivers fast, clean drilling with minimal burrs. The split-point tip provides accurate positioning, eliminates wandering, and ensures straight holes every time.

Complete Metric Size Set

This set includes a full range of metric sizes from 1mm to 6.5mm (25 pieces), covering all common drilling needs for household repair, woodworking, metalworking, construction and DIY projects. No need to purchase individual bits, one set meets all your requirements.

Sturdy Metal Storage Case

All bits are neatly organized in a durable metal storage case with clear size markings, making it easy to find the right bit quickly, protect the bits from damage, and carry them to job sites or store in your toolbox.
