1. Product Specification
This all-rounded 11pc Multi-Purpose Diamond Drill Kit with Aluminum Storage Case is a full-spec renovation drill package that covers nearly all common stone, tile and glass drilling needs in home upgrades and commercial decoration. The full 11pc Multi-Purpose Diamond Drill Kit with Aluminum Storage Case assembles 11 differentiated drill pieces: spear-tip glass drill, threaded conversion adapter, slim long diamond drills, medium and large golden coated hole saws, hexagonal grinding burrs and various aperture hole cutters, with bore diameters spanning 6mm to 35mm to satisfy micro positioning holes all the way to large sink cutouts.
Every drill contained in the 11pc Multi-Purpose Diamond Drill Kit with Aluminum Storage Case adopts premium vacuum brazed exposed diamond grit craftsmanship. The drill pieces come with diversified overall lengths ranging from 33mm to 72mm and matched working lengths for different drilling depths. Two mainstream shank designs are integrated into this 11pc Multi-Purpose Diamond Drill Kit with Aluminum Storage Case: hexagonal shanks fit regular cordless electric drills, while threaded shanks adapt to angle grinders, removing the trouble of purchasing extra adapters. Golden anti-rust baking paint coats most hole saw bodies to resist erosion from stone dust and dampness. The customized shockproof aluminum storage case of the 11pc Multi-Purpose Diamond Drill Kit with Aluminum Storage Case has individually molded slots, which can stably fix each separate drill, protecting delicate diamond grit from collision, abrasion and falling off during delivery and frequent job-site movement. The entire kit is applicable to vitrified tiles, glazed ceramic, marble, granite, quartz stone, natural slate and ordinary glass.
2. Craft & Performance
The competitive edge of the 11pc Multi-Purpose Diamond Drill Kit with Aluminum Storage Case comes from optimized vacuum brazing technology and targeted structural designs for varied working scenarios. All diamond abrasive areas undergo rigorous high-temperature vacuum welding, tightly bonding industrial diamond particles to avoid the frequent grit shedding issue of cheap electroplated drills. The spear-tip glass drill achieves precise initial positioning to prevent slip on glossy tile surfaces. Slim elongated drill bits are suitable for narrow deep holes, while hole saws reserve side chip removal openings to quickly discharge stone powder and cut down jamming and overheating risks. Hexagonal grinding burrs work excellently for trimming rough hole edges and deburring after drilling. Precision CNC machining delivers smooth shank surfaces for tight clamping and stable rotation.

FAQ
Q1: What power tools can work with the 11pc Multi-Purpose Diamond Drill Kit with Aluminum Storage Case?
A: Bits fitted with hexagonal shanks can be clamped by standard cordless electric drills, while threaded-shank drills need to be installed on matched angle grinders. Do not use hammer impact mode when drilling tiles and glass.
Q2: Must I use cooling water while drilling?
A: Dry drilling is workable for most daily scenarios. Pause for roughly 30 seconds after two consecutive minutes of drilling for heat dissipation; mild water cooling is recommended if you process thick granite or fragile glass for smoother outcomes.
Q3: What materials are not fit for this drill set?
A: Reinforced concrete, thick tempered glass and solid hard metal plates should be avoided, as these materials will rapidly abrade the diamond grit.
Q4: Can I customize the aluminum box and drill specifications?
A: Yes, Changshunda supports bulk customization of the 11pc Multi-Purpose Diamond Drill Kit with Aluminum Storage Case. You can customize logos, adjust the combination of drill apertures and redesign the layout of internal box slots.
Q5: How to maintain the kit after construction work?
A: Brush stone and glass dust off each drill gently, air-dry all components thoroughly, then place drills back into corresponding slots inside the aluminum case, and store the sealed case within dry indoor environments.
