55199140 Impact Piston Sandvik HLX5 rock drill drifter parts 551 991 40 Tamrock Piston

Sandvik HLX5 Impact Piston – Part No. 55199140

The Sandvik HLX5 impact piston (part number 55199140) is a direct replacement for worn or failed pistons in HLX5 rock drill drifters. It transfers percussive energy from the drill's hammer to the drill steel, and at 10kg it's built to handle tough rock conditions without adding unnecessary weight. This is a genuine Sandvik part, so you're not gambling with aftermarket tolerances. We keep it on the shelf, ready to ship when you need it.

FAQ
FAQ
Will this piston fit my Tamrock HLX5?
Yes. Tamrock HLX5 and Sandvik HLX5 are the same drifter. This piston fits both.
How do I know if I need a new piston?
Look for loss of impact power, unusual vibration, or visible scoring/damage on the piston surface. If the drifter isn't hitting as hard as it used to, this is a common culprit.
How quickly can you ship this piston?
We have it in stock. Orders placed before 2pm ship the same business day. International shipping typically takes 3-7 days depending on location.
Is this a genuine Sandvik part?
Straight from Sandvik. Not a copy, not 'OEM equivalent'. We source directly from authorized channels.
What's the weight of the piston?
10kg. That's an important spec because it affects impact energy and drill balance. Don't substitute with a piston of a different weight.
