Premium Laser Welded Concrete Core Drill Bit 1–16 in

1. Product Overview

The Alskar Premium Laser Welded Concrete Core Drill Bit is a Premium-grade option for concrete and reinforced concrete coring. Designed to cut through concrete containing embedded steel reinforcement, it is suited to construction and building-services openings where the bore may intersect rebar.

The segmented cutting crown uses 10mm-high diamond segments laser-welded to the steel barrel. This series combines a 14-inch (355.6mm) tube length, excluding the connection hub, with a standard diameter range of 1–16 inches. Segment width varies by diameter and follows the specified configuration for the selected bit.

Choose the bit according to the required hole diameter, effective drilling depth, concrete conditions and machine capacity. For the wet-coring setup described here, use compatible water-fed diamond core drilling equipment. The stated tube length excludes the connection hub. Overall length and effective drilling depth are separate specifications.

The 1-inch size uses a 5/8″-11 connection, while other supplied standard sizes use 1-1/4″-7. Other diameters can be made to customer requirements. For a custom size or another machine interface, send the required dimensions, connection details and drilling conditions so Alskar can confirm the configuration, price and lead time.

2. Core Selling Points

Concrete & Reinforced Concrete Coring

Designed for concrete coring, including cutting through steel reinforcement embedded in the concrete along the drilling path.

Laser-Welded Diamond Segments

The diamond segments are attached to the steel barrel by laser welding. Laser-welded construction is a defining feature of this Premium series.

Premium Quality Grade

A Premium-grade choice in the Alskar core bit range for contractors and project buyers specifying concrete and reinforced concrete drilling tools.

10mm Segment Height

The standard series uses 10mm-high diamond segments. Segment width is specified according to the selected bit diameter.

14-Inch Tube Length

The standard tube length is 14 inches (355.6mm), excluding the connection hub. Confirm overall length, effective drilling depth and machine clearance for the selected setup.

1–16-Inch Standard Diameter Range

Choose the diameter required for the concrete opening and match it to the capacity of your drilling equipment.

Custom Sizes Available

Other diameters can be made to order. Send your required size, quantity and project details for configuration review and a quotation.

3. Recommended Applications

• Concrete and reinforced concrete coring.
• Concrete openings where the drilling path includes embedded rebar.
• Pipe, conduit and building-services penetrations through concrete walls and slabs.
• Project-specific concrete openings requiring custom bit diameters.

For selection support, provide the concrete conditions, anticipated reinforcement, required diameter and working depth.

4. Equipment & Connection Matching

Use compatible diamond core drilling equipment with sufficient diameter capacity and working clearance. For wet coring, select a suitable water-fed setup and the stand arrangement specified for your drilling machine and bit size.

Provide the drill brand and model, spindle specification, male/female orientation and a connection photo or drawing when requesting an alternative interface. A matching thread label alone does not establish full machine compatibility.

8. Size Specifications — Product Entry Working Table

Metric values above are arithmetic conversions of the inch sizes, not separate nominal metric products or diameter tolerances. For an exact metric hole requirement, specify that dimension in the custom inquiry.

Segment width is the diamond cutting segment width, not the steel tube wall thickness. .140 in = 3.556mm; .150 in = 3.810mm; .155 in = 3.937mm; .180 in = 4.572mm.
