Corona diamantata Distar RS-TX 1 1/4" 62 mm x 300 mm

Distar RS-TX diamond core bit with a 1 1/4" connection, 62 mm cutting diameter and 300 mm overall length is designed for coring holes in concrete, reinforced concrete, masonry and other mineral materials. The tool is suitable for both dry and wet drilling and is intended for use with rotary drills and core rigs when creating openings for plumbing, electrical conduits and construction penetrations.

Advantages

The RS-TX design uses industrial diamond segments engineered for prolonged service life and steady cutting rates. A robust bond between segments and the steel body improves durability under heavy load, while the 1 1/4" threaded connection ensures compatibility with a wide range of hand-held rotary drills and coring machines. The 62 mm diameter provides a standard-sized hole for common installation tasks, and the 300 mm length offers sufficient reach for through-holes and wall penetrations.

Suitable for

• Coring holes in concrete and reinforced concrete
• Installing plumbing and sanitary pipe penetrations
• Creating openings for electrical conduits and wiring
• Drilling through masonry, brick and other mineral substrates
• Dry or wet coring on construction sites and renovation projects

Key specifications

• Connection: 1 1/4" threaded
• Cutting diameter: 62 mm
• Total length: 300 mm
• Cutting segments: industrial diamond
• Suitable drilling methods: wet and dry coring
• Compatible equipment: rotary drills and core rigs with 1 1/4" connection

How to use

Secure the core bit to a compatible rotary drill or core rig with a 1 1/4" connection following the machine manufacturer's instructions. Position the bit at the marked drilling location, start at low speed to establish the pilot contact, then increase speed and apply steady axial pressure while allowing the diamonds to cut. For wet coring, provide a continuous water feed to cool the bit and flush out debris. For dry coring, use intermittent operation to avoid overheating and periodically withdraw the bit to clear chips.

Recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and dust control when dry cutting. Select wet cutting when possible to extend segment life and reduce dust. Match drill speed and feed pressure to the material hardness; excessive force or incorrect speed can reduce cutting performance and segment life.
