Diamond-tipped Hex Drill Bit INDIAN PROFESSIONAL KORONA 6 mm — dry drilling

Diamond-tipped hex shank drill bit INDIAN PROFESSIONAL KORONA, 6 mm diameter, designed for dry drilling of hard and abrasive materials. The bit combines a diamond-coated tip with a hexagonal shank to provide secure retention in chucks and bit holders, enabling precise hole-making when coolant or water is not used. Intended for tradespeople and DIY users who need reliable, repeatable drilling performance on demanding surfaces.

Advantages

The diamond-coated cutting edge delivers high wear resistance and consistent cutting action on abrasive materials. The hexagonal shank ensures a stable grip in impact drivers, quick-change chucks, and bit holders, reducing slippage during use. The compact 6 mm diameter is suited to creating precise holes with minimal material disruption during dry drilling. The bit is optimized for tasks that require both accuracy and durability without reliance on cooling fluids.

Suitable for

• Drilling small-diameter holes in abrasive tile, porcelain and ceramic surfaces
• Working with stone, engineered stone and certain masonry materials where dry drilling is necessary
• On-site jobs where water or coolant cannot be used
• Precision tasks in renovation, installation and carpentry that require a compact, robust bit

Key specifications

• Tip: diamond-coated cutting surface for abrasion resistance
• Shank type: hexagonal for secure retention
• Diameter: 6 mm
• Intended use: dry drilling
• Compatibility: suitable for chucks, quick-change holders and impact drivers that accept hex shanks
• Application materials: ceramic, porcelain, tile, stone and similar abrasive surfaces

How to use

Mark the drilling point and secure the workpiece to prevent movement. Fit the hex shank firmly into the chuck or bit holder and set the drill to an appropriate speed for the material; moderate to low speeds are typically recommended for diamond-tipped bits in hard or brittle surfaces. Apply steady, light pressure and allow the diamond tip to cut—avoid excessive force that can cause overheating or bit damage. Periodically withdraw the bit to clear debris and inspect the hole. Since the bit is designed for dry drilling, do not introduce liquid coolant unless the tool manufacturer and workpiece allow it.

Usage recommendations

For longer bit life and cleaner holes, start with a small pilot mark or use a center punch on smooth surfaces, control rotational speed, and maintain steady pressure; replace the bit when cutting performance visibly decreases to avoid damaging the workpiece.
