SHDIATOOL Diamond Core Drill Bit 35mm (1-3/8 in) for Hard Stone and Concrete | Dry or Wet, 5/8-11

Introducing the SHDIATOOL Diamond Core Drill Bits, engineered to tackle tough materials with steady, reliable performance. The 1-3/8 inch (35 mm) core bit features laser welded diamond segments that stay engaged under load, helping you maintain a smooth, controlled cut through hard stone and masonry. With a compact total length of 100 mm, it offers good balance and reach for a variety of projects, from countertop openings to masonry work.

Key specs at a glance include diameter 35 mm, total length 100 mm, and a 5/8 inch-11 thread. These measurements provide a practical combination of bite and reach, enabling efficient hole creation without sacrificing maneuverability on the jobsite.

Dry or wet drilling? You can choose based on your task and workspace. Dry drilling is convenient for quick, on-the-fly holes, while wet drilling helps cool the cutting edge and can prolong the life of the diamond segments. Using water may also reduce dust and heat buildup, contributing to cleaner cuts and steadier performance.

Designed for drilling hard granite, marble, engineering stone, concrete, and brick, this core bit aims to deliver predictable results across challenging surfaces. The laser welded segments are built to resist wear during long runs, helping you maintain a steady cutting action and minimize stalling or vibration in demanding jobs.

Usage and compatibility are straightforward. The bit is designed to operate on a 5/8 inch-11 angle grinder. If you need to adapt it for other machines, look for appropriate adapters for SDS, hex, or round shanks. Always pair the tool with proper safety gear and follow manufacturer guidelines for speed and cooling to optimize performance.

Why consider SHDIATOOL core bits? The combination of a robust diamond segment construction, a precise 35 mm diameter, and compatibility with common grinder setups makes this bit a flexible option for professionals and DIY enthusiasts tackling stone and concrete projects. While results depend on technique and conditions, users may experience clean holes, steady cutting action, and dependable durability in typical workflows.

Whether you are upgrading an existing toolkit or starting a stone and masonry project, this 35 mm SHDIATOOL core bit offers a balance of precision, durability, and adaptability that can help you approach hard substrates with confidence.
