1. Product Specification
This practical 5pc M14 Color Exposed Sand Drill Plastic Box is a compact diamond drilling kit designed for daily renovation small-hole cutting work. The complete 5pc M14 Color Exposed Sand Drill Plastic Box contains 5 commonly used drill sizes: 6mm, 8mm, 10mm, 12mm, plus one extra 6mm spare drill bit, matching most small aperture drilling demands for home decoration and engineering construction.
All drill bits adopt standard M14 threaded shank, perfectly compatible with mainstream M14 angle grinders without extra adapters. To facilitate quick size identification, drill bits are designed with two colors: 6mm drill bits are red coated, while 8mm, 10mm and 12mm drill bits are blue coated. Equipped with a durable transparent plastic box, this 5pc M14 Color Exposed Sand Drill Plastic Box features independent fixed slots inside, preventing drill bits from collision and diamond grit wear during transportation and storage. Each drill bit has a total length of 60mm and effective cutting depth of 35mm, supporting efficient one-time dry drilling for stone and ceramic materials.
2. Craft & Performance
Adopting professional vacuum brazed exposed sand technology, every drill bit inside the 5pc M14 Color Exposed Sand Drill Plastic Box owns firmly bonded diamond abrasive grains, solving the common grit falling-off problem of ordinary electroplated drill bits. The fully exposed sand cutting edge delivers sharp cutting performance, realizing water-free dry drilling without cooling water. The colored anti-rust paint not only helps users distinguish sizes rapidly, but also protects drill bodies from rust and corrosion caused by stone dust and moisture. Smooth M14 threaded shank ensures tight connection with angle grinders, no slipping or loosening during high-speed working. Below is the detailed product parameter table:
