The EX430, EX530 or EX538 Drill Attachment is custom built to fit your excavator model, these Excavator Attachments offer solutions for a variety of rock drilling applications such as: 
Small hole diameter drilling of 32mm - 76mm depending on the drifter type and model
Percussion Drilling using Hydraulic Drifters or Pneumatic Drifters 
Core Drilling
 
The same small EX-Aluminium Drill mast is used for the EX430, EX530 and EX538 attachments. On these units we fit the hydraulic drifter or pneumatic drifter that best suits your needs. The purpose of these attachments is to offer a very lightweight attachment for small hole diameter drilling in hard rock and tight areas. The smaller hydraulic drifters require less hydraulic oil flows from the carrier unit. If you dont have the hydraulic oil flow for the hydraulic drifters you can also opt for the Pneumatic drifters which offer up to 10kW of energy. 
The EX430, EX530 & EX538 attachments come with many optional extras to choose from such as:
Dust Suppression 
360 degree rotator/s
Multiple Mast Lengths available
Centraliser
Pressure Washer Attachment
Shipping and Storage Platform
Remote Controls (2 options available)
Air Swivel
WEM Excavator Mount
Angle Indicator (x, y)
Line Oiler
Energy Chain for Hydraulic Hose handling (for extended mast mainly)
Quick Change Drifter Mount
