SOIL REAMING TOOLING

Barrel Reamer

Engineered for bore conditioning and a stable, full-diameter profile in suitable soil, the DRILLNOVA Barrel Reamer combines a long barrel body with carbide cutters, fluid ports and application-matched wear protection. Diameter, connections and rear configuration are confirmed for the ground conditions, bore plan and drill string.

Application

HDD soil reaming and bore conditioning

Formation

Sandy loam to stable medium soil

Cutting System

Carbide cutters with wear-zone protection

Rear Interface

Pulling eye or rated swivel interface

Product Overview & Application

Overview

The DRILLNOVA Barrel Reamer is a full-body soil reamer designed to condition the pilot bore while supporting a round, stable profile during enlargement. Its long barrel geometry helps maintain the reamed diameter, while carbide cutters, fluid ports and wear protection assist cutting and spoil movement. It is intended for suitable, reasonably stable soils rather than competent hard rock or uncontrolled running ground.

Full-Body Bore Conditioning

Long barrel geometry supports a round, full-diameter bore profile through the reaming pass.

Carbide Cutting Support

Carbide cutters are arranged to assist soil cutting and bore conditioning for the confirmed application.

Fluid and Spoil Movement

Fluid ports are configured to support cleaning and spoil movement around the tool body.

Project-Matched Interfaces

Front connection, rear option and overall configuration are confirmed against the rig, drill string and pullback plan.

Use, Quality & Documentation

Use & Installation

Confirm the front connection, rear interface and approved assembly arrangement before use. Review thread engagement, tool alignment, bore diameter and the planned reaming sequence. Operate only within the parameters supplied with the confirmed tool configuration.

Inspection & Service

After each run, clean and inspect the carbide cutters, hardfacing, fluid ports, barrel body and front and rear interfaces. Record unusual wear, cracking, deformation, blocked ports or connection damage before the next pass. Service or replace affected components in accordance with the approved inspection criteria.

Handling & Storage

Use the approved lifting and handling plan for the tool's size and mass. Protect cutters and connection surfaces from impact and contamination. Support the long body securely during transport, and store the reamer clean and dry with protected interfaces.

Product FAQ

What is a Barrel Reamer used for?

A Barrel Reamer is used in horizontal directional drilling to enlarge and condition a pilot bore in suitable soil. Its long, full-body geometry helps support a round, stable bore profile during reaming.

Which formations are suitable for this Barrel Reamer?

The primary formation window is sandy loam through stable medium soil, including loam and loamy clay. Fine gravel, unstable running ground and ground with a high packing tendency require additional application review.

What sizes are available?

The catalog lists configured diameters from 8-48 in / 200-1,200 mm. Larger custom sizes may be available after engineering review.

Can a Barrel Reamer be used in hard rock?

This Barrel Reamer is not recommended for competent hard rock. A rock-specific reamer or roller-cone hole opener should be reviewed for those conditions.

What rear connection options are available?

The catalog lists a pulling eye or a rated swivel interface. The final option, geometry and rating are confirmed for the pullback arrangement at order.

Can the body length and connections be customized?

Yes. Body length is application-specific, while the front box connection is selected for the rig and tool string. Final details must be confirmed during the technical review.

What project information is required for selection?

Provide the geotechnical information, bore profile, pilot-hole size, target diameter, planned reaming stages, rig model and capacity, drill-string connection, fluid system and expected cuttings-return conditions.

What should be inspected after each run?

Inspect the cutters, hardfacing, fluid ports, barrel body and both connection interfaces. Any unusual wear, cracking, deformation, blockage or connection damage should be recorded and reviewed before reuse.
