Diamond hole saw MILWAUKEE DISTAR ROCKET 68 x 45-8 x M14, segmented diamond cutting core for wet/dry drilling

Diamond hole saw MILWAUKEE DISTAR ROCKET 68 x 45-8 x M14 is a segmented diamond cutting core engineered for drilling precise circular holes in hard surfaces. The tool has a 68 mm cutting diameter, 45 mm cutting depth and an M14-threaded arbour suited for common rotary tools and angle grinders. Designed for both wet and dry drilling, this diamond hole saw is intended for use on ceramic tile, porcelain, natural stone and similar masonry where clean edges and controlled cutting are required.

Advantages

The segmented diamond rim promotes efficient material removal and reduced clogging during drilling, while the segmented design helps dissipate heat for longer life during both wet and dry operations. The M14 thread makes attachment straightforward to compatible power tools, and the 45 mm cutting depth allows through-holes and deeper penetrations common in tile installation and stone work. The construction balances cutting speed and edge quality to produce accurate, round holes with minimal chipping on finished surfaces.

Suitable for

• Drilling holes for plumbing, electrical boxes and fixtures in ceramic and porcelain tile
• Creating openings in natural stone and engineered stone for sinks and taps
• Cutting pass-through holes in masonry during renovation and installation work
• Use with angle grinders and rotary tools that accept M14-threaded arbors

When it may not be suitable

This segmented diamond core is not intended for prolonged continuous cutting in reinforced concrete or very abrasive building materials; performance and lifetime may be reduced on such substrates. Extremely thin tiles or fragile decorative veneers may crack if excessive feed pressure or incorrect tool support is used.

Key specifications

• Cutting diameter: 68 mm
• Cutting depth: 45 mm
• Arbour thread: M14
• Segmented diamond rim for wet and dry drilling
• Suitable materials: ceramic tile, porcelain, natural stone, masonry

How to use

Attach the hole saw to a compatible power tool with an M14 arbour and secure it according to the tool manufacturer’s instructions. For best results, start drilling at low speed to establish a pilot groove, then increase speed while applying steady, moderate pressure. Use water cooling where possible to reduce heat and extend the tool life; if dry drilling is necessary, operate with intermittent cutting to avoid overheating. Support the workpiece to prevent movement and reduce the risk of chipping; maintain a perpendicular angle to obtain a clean round hole.

What to consider before purchase

• Confirm the power tool accepts an M14-threaded arbour
• Match cutting diameter and depth to the required hole size for your installation
• Consider whether wet cooling is available for longer tool life
• Assess the substrate type—very hard or reinforced concrete may require a different product

Usage recommendations

Use steady, moderate feed pressure and, when possible, wet drilling to prolong segment life. Secure the workpiece, start at low speed to position the hole saw, and avoid excessive lateral force to minimise chipping and ensure accurate circular cuts.
