BGTEC Dry Diamond Drill Bit Set – 10pcs, 6mm (1/4”), Vacuum Brazed Core Bits for Granite, Marble, Tile

BGTEC Dry Diamond Drill Bit Set is engineered to empower precise, clean drilling across a variety of materials. This 10‑piece kit features a 6mm (1/4") diameter bit with an 8mm diamond tip and a round shank for stable performance in dense stone and smooth substrates alike. The combination of vacuum brazed diamond technology and a built‑in wax‑core cooling system supports efficient cutting without the overhead of water‑based drilling.

Key capabilities

• Multi‑material compatibility: granite, marble, masonry, concrete, tile/ceramic, glass, and hard plastic.
• Wax‑core cooling and lubrication provide heat management to help control friction during dry drilling.
• Side hole and groove design aids chip removal for less clogging and steadier progress.
• Dry drilling option delivers convenience and less mess; water can be used when extended bit life is desired.

Performance and durability

• Vacuum brazed diamond technology delivers high efficiency, faster cuts, and resilient edges for repeated use.
• Diamond length of 8mm and a robust round shank enable steady alignment and reduced bit wobble.

Practical tips

• Begin with light pressure and steady speed to optimize edge quality on ceramic and tile surfaces.
• Use a pilot hole on hard substrates to guide the bit and prevent wandering.

What you get

The BGTEC Dry Diamond Drill Bit Set offers reliable performance for home renovations, cabinetry, or light professional tasks, delivering consistent results across stone, tile, glass, and plastic materials.

Notes on expectations

While designed for dry use, results depend on material type and technique. The kit suggests potential improvements in drilling speed, chip control, and edge quality, without guaranteeing outcomes.
