## Summary description

Diamond core drill bit INDIAN PROFESSIONAL KORONA, M14 shank, 20 mm cutting diameter designed for dry drilling. Intended for cutting and coring hard materials where a diamond-segment tip is required. Features standard M14 thread compatibility for grinders and drilling tools, suitable for tradespeople and DIY use in masonry, tile or stone applications.

## Long description

Diamond Core Drill Bit INDIAN PROFESSIONAL KORONA M14 20 mm for Dry Drilling is a purpose-designed cutting tool for coring small-diameter holes in hard building materials. The 20 mm cutting diameter and diamond-segment tip make the bit suitable for working with masonry, ceramic tiles, natural stone and similar surfaces where abrasion resistance and precise cutting are required. The M14 shank and thread provide direct compatibility with angle grinders and other rotary tools that accept M14 fittings, enabling dry drilling applications without the need for a separate arbor.
Advantages
The diamond-segment cutting edge delivers durable abrasion resistance and consistent cutting performance during dry drilling. The M14 threaded shank ensures secure mounting to compatible grinders and reduces runout for more accurate holes. With a compact 20 mm diameter, the bit allows controlled coring and minimal material removal for neat openings. The design balances cutting speed and longevity for trade and DIY tasks on hard surfaces.
Suitable for
 Coring 20 mm holes in ceramic and porcelain tiles
 Drilling holes in masonry and concrete blocks
 Cutting openings in natural stone and engineered stone
 Dry drilling applications with M14-compatible angle grinders and rotary tools
Key specifications
 Cutting diameter: 20 mm
 Tip type: Diamond-segment for dry cutting
 Shank/thread: M14 threaded shank for direct mounting
 Intended use: Dry coring of hard materials such as tiles, stone and masonry
How to use
Secure the M14 diamond core bit onto a compatible angle grinder or rotary tool following the tool manufacturer’s mounting instructions. Mark the drilling position and start at low speed to establish the cutting groove, then apply steady, moderate pressure while maintaining tool stability. Use intermittent pulling motions or brief pauses to reduce heat buildup during dry drilling. Keep the workpiece stable and support fragile tiles from the rear when coring to avoid cracking. Wear appropriate personal protective equipment including eye protection, dust mask and hearing protection.
Usage recommendations
For best results when dry drilling with this diamond core bit, begin at slower speeds and avoid excessive lateral pressure. Allow the diamond segments to wear gradually rather than forcing the cut; this extends tool life. If possible, periodically cool the bit with short breaks or by using a light misting technique recommended by the tool manufacturer, where safe. Replace the bit when cutting becomes slow, uneven, or if segments show significant wear.
