FAQ
Q1: What power tools can the 16pc red exposed sand dry drill cloth bag match?
A: All drill bits inside the 16pc red exposed sand dry drill cloth bag adopt standard 10mm triangle shank, compatible with all corded/cordless hand electric drills and bench drills with 3/8 inch chuck. It cannot be used on angle grinders or impact hammer drills, impact mode will cause diamond grit to fall off rapidly and damage the drill body of the 16pc red exposed sand dry drill.
Q2: Does the 16pc red exposed sand dry drill cloth bag need water cooling during drilling?
A: No mandatory water cooling required. The whole 16pc red exposed sand dry drill cloth bag adopts vacuum brazed exposed diamond sand craft with built-in solid cooling wax specially designed for dry cutting. You can directly drill tiles, marble and granite without spraying cooling water, very convenient for outdoor construction sites without water supply. But continuous dry drilling over 3 minutes needs to pause for 30 seconds for natural heat dissipation to extend the service life of each 16pc red exposed sand dry drill bit. Short-time wet drilling is also supported for ultra-hard granite to further reduce bit wear.
Q3: What materials cannot be drilled with the 16pc red exposed sand dry drill cloth bag?
A: The 16pc red exposed sand dry drill cloth bag is suitable for vitrified tile, ceramic, marble, granite, quartz stone, slate, artificial stone; it is not recommended for reinforced concrete, thick float glass, metal steel plate, hard brick, which will cause severe abrasion and grit shedding of the exposed diamond sand of the 16pc red exposed sand dry drill bits.
Q4: Will the tile crack when using the 16pc red exposed sand dry drill cloth bag for dry drilling?
A: The exposed sand cutting crown of the 16pc red exposed sand dry drill is evenly inlaid with sharp diamond grains with built-in cooling wax. When starting drilling, slightly lower the electric drill rotation speed, keep the drill vertical to the tile surface and apply light even pressure, tiles will not crack during dry drilling. For ultra-thin 3-6mm vitrified tiles, you can stick anti-slip masking tape on the drilling position to further avoid edge chipping.
Q5: How to maintain and store the 16pc red exposed sand dry drill cloth bag after use?
A: After finishing drilling work, use a hard brush to clean stone dust residue on each 16pc red exposed sand dry drill bit, place the drill in a ventilated place to completely dry, then insert each drill into the fixed independent slot of the matched cloth storage bag, zip up the bag and store in dry tool cabinet. This operation can effectively prevent the exposed diamond grit from colliding and falling off, and avoid the red metal drill body getting rusty from damp stone dust.
Q6: Can I customize the size combination and brand logo of the 16pc red exposed sand dry drill cloth bag?
A: Yes, Changshunda factory supports full OEM customization of the 16pc red exposed sand dry drill cloth bag. You can adjust the diameter matching quantity inside the set, customize exclusive brand laser marking on drill body, print your independent station store logo on the storage cloth bag, and customize color box outer packaging for your brand sales.
Q7: What’s the average service life of single drill bit from the 16pc red exposed sand dry drill cloth bag?
A: Under normal light construction use, each drill piece of the 16pc red exposed sand dry drill cloth bag can complete over 220 clean holes on medium-hard marble and ordinary ceramic tiles. If used for continuous drilling of ultra-hard black granite, the service life will be slightly reduced, but still 3-5 times longer than ordinary electroplated diamond drill bits sold on global market.
Q8: Why triangle shank is better than round shank for the 16pc red exposed sand dry drill cloth bag?
A: Round shank drill bits easily slip inside electric drill chucks under high-speed rotation, causing scratched workpiece surface and broken tiles. The triangle shank of the 16pc red exposed sand dry drill cloth bag forms three-sided full contact locking with chuck jaws, zero slipping during dry drilling, greatly improve hole precision and reduce workpiece scrapping rate for professional workers and DIY users.
