VK 4611D Rivet Buster

Rivet Buster – VK 4611D ( 34 lb )

The VK 4611D is a 15.5 kg rivet buster, technically equivalent to the Chicago Pneumatic CP 4611D, and known in the field as the Hell Dog or Boyer Buster. Its 279 mm long cylinder stroke trades blow rate for blow energy, at 720 blows per minute on 21 l/s of air, which is what heavy concrete demolition and large rivet cutting call for. The D handle with inside trigger and stepped cylinder design prevent accidental piston ejection. It replaces the earlier VK 4181.

Application

• Bridge deck work with weight restrictions

• Medium to heavy concrete demolition

• Cutting metal tanks or plates

• Industrial applications in foundries or the petrochemical industry

Features

• Teasing Throttle for smooth performance and operator control

• Operation under tough conditions

• Stepped cylinder design to prevent accidental piston ejection

• “D” handle with inside trigger

• Robust components for enduring tough work environments

• New Design VK 4611D replaces the old VK 4181 (11” long cylinder stroke)

VK 4611D Rivet Buster FAQs

Can the VK 4611D replace a CP 4611D?

Yes. The VK 4611D is technically equivalent to the Chicago Pneumatic CP 4611D, manufactured by Vikay in India. A 30.2 mm piston on a 279 mm stroke gives 720 blows a minute at 15.5 kg on 21 l/s of air at 6.2 bar.

Will Vikay parts fit my CP 4611D?

Yes. Vikay manufactures the VK 4611D, which is technically equivalent to the Chicago Pneumatic CP 4611D, and the replacement parts alongside it. The same parts serve both, so a machine already in service can be kept running on them. The listing, with part numbers and the assemblies they belong to, is on the CP 4611D Chicago Pneumatic Rivet Buster Parts page.

Which Vikay rivet buster do I need?

This page is the VK 4611D at 15.5 kg. Three sizes are manufactured, each in a D handle and a pistol grip version. The 4608 is the lightest at about 14 kg, the 4611 the middle at about 15 kg, and the 4689 is the riveting hammer, which converts to a rivet buster by fitting a retainer and a chisel. The handle is a separate decision from the size: the D handle for sustained two handed work on rivets and concrete, the pistol grip for tight spaces and overhead.

Will my compressor run the VK 4611D?

The VK 4611D needs 21 l/s at 6.2 bar, delivered continuously. The inlet is 12.7 mm, so run at least that hose bore: anything narrower throttles the machine before the compressor does. At 720 blows a minute the draw is constant rather than intermittent, so size the compressor against that figure rather than against a peak.
