Xpress Turbo Core Drill Bits

Patterned diamond segments / Wet drilling / For reinforced concrete and very hard concrete / 14" standard barrel length

Professional Wet Core Drill Bits for Reinforced and Very Hard Concrete

Wet core drilling requires a bit capable of maintaining drilling speed, segment durability, and stable performance in reinforced and very hard concrete.

DIATOP XPRESS CORE DRILL BITS are high-performance diamond core drill bits designed for fast drilling and long service life.

The new patterned diamond segments are designed to drill faster and provide longer life, while supporting high-efficiency drilling in reinforced concrete and very hard concrete.

A 14" barrel length is standard, with other barrel lengths available upon request.

Q1. What core drill bit is recommended for reinforced and very hard concrete?

A. DIATOP XPRESS CORE DRILL BITS are designed for wet drilling in reinforced concrete and very hard concrete. They use patterned diamond segments for faster drilling and longer life.

Q2. What bond should be selected for different drilling conditions?

A. The catalog specifies SC for very hard aggregate with heavy reinforcing, MC for hard aggregate with light reinforcing, and HC for asphalt and block.

Q3. What sizes and thread are available for XPRESS CORE DRILL BITS?

A. XPRESS CORE DRILL BITS are available from 2 inch (51 mm) to 16 inch (406 mm) diameter, with segment specifications and segment counts varying by size. The standard thread is 1 1/4-7, and the standard barrel length is 14".
