Drilling Accessories & Auxiliary Tools

Other Parts

Back hammer

The back hammer is designed to assist in pulling out the drill string. During stuck-hole or collapsed-hole operations, it can significantly reduce downtime and operational costs, improving overall drilling efficiency.

Technical Specifications

Model	Air pressure, bar	Connection thread	Diameter, mm	Weight, kg
6'' back hammer	8-15	API 3 1/2'' REG	192	71.5
10'' back hammer	8-15	API 3 1/2'' REG	273	130.5
14'' back hammer	8-15	API 5 1/2” REG	325	201

Other specifications are available upon request.

Breakout bench

A fully automatic hydraulic breakout bench designed for easy and efficient disassembly of drilling tools. The bench is user-friendly, fast to operate, and suitable for high-frequency on-site operations.

Technical Specifications

Model	Dimensions (L x W x H), mm	Hydraulic tank capacity, L	Weight, kg
3''-6'' breakout bench	820x850x1000	40	400
6''-8'' breakout bench	1320x920x920	70	690
8''-12'' breakout bench	1400x1140x1180	70	820

Shock Absorber

Effectively absorbs reverse impact forces generated by the DTH hammer, protecting the drill rig power head, especially critical in large-diameter drilling applications.
Available in two structural designs: Threaded type for water well drilling, oil & gas, shale gas, and geothermal applications; Hexagonal type primarily used in large-diameter foundation piling projects.
Compatible with DTH drilling rigs, water well rigs, piling rigs, rotary drilling rigs, and related equipment.

Technical Specifications

Model	Max. buffer stroke, mm	Elastic component	Connection thread	Dimensions (Ø x L), mm	Weight, kg
6'' absorber	25	PU washer	API 3 1/2'' REG	182 x 565	100
12'' absorber	75	Disc spring	API 6 5/8'' REG	273 x 885	300
18'' absorber	125	Disc spring	Hexagonal 273	278 x 1400	345

Tube drawing Bench

A compact and lightweight device specifically designed for casing extraction. Its narrow structure allows operation in confined or limited-access sites, making it ideal for small pits and restricted job sites.
