2. Craft & Performance
All drilling tools of the M14-15pc Black Exposed Diamond Set with Aluminum Storage Case are manufactured by high-temperature vacuum brazing technology, the core craft that supports stable cutting performance and long lifespan of the M14-15pc Black Exposed Diamond Set with Aluminum Storage Case. The open exposed diamond grit layout on each cutting head of the M14-15pc Black Exposed Diamond Set with Aluminum Storage Case creates wide chip clearance gaps, quickly washing away stone powder with cooling water and effectively preventing drill clogging during long-hour continuous drilling. The matte black anti-corrosion coating on 45# steel body of the M14-15pc Black Exposed Diamond Set with Aluminum Storage Case resists water and oxidation, avoiding rust even in humid wet construction environments.
The tight vacuum brazing fusion firmly locks diamond grit to prevent shedding under high-speed rotation and heavy torque load. Thickened solid 45# steel base resists bending and deviation, producing smooth burr-free round holes without tile chipping. The matched 50mm chamfer cone of the M14-15pc Black Exposed Diamond Set with Aluminum Storage Case polishes smooth rounded edges for countertops, while the M14 to hex adapter expands compatibility to cordless electric drills besides angle grinders. The unified 60mm short body design of all core bits allows operation in narrow confined gaps, greatly improving the scene adaptability of the M14-15pc Black Exposed Diamond Set with Aluminum Storage Case.
