RH 658 LS - Sinker Drill

RH 658 5L vs RH 658 LS — What's the Difference?

The RH 658 LS (8311 0302 87) is built on the same drilling core as the RH 658 5L (8311 0302 77), with one additional feature of an added silencer with the tool. This reduces the level of the sound and thus provides comfort to the ears of the operator while drilling underground confined places.

The RH 658LS weighs 1 kgs more than the standard RH 658 5L, which is the weight of the additional silencer. But this change in weight does not affect the drilling performance.

In short: pick the RH 658 5L if noise is not a concern on your site. Pick the RH 658 LS if your operators are running long shifts, working in confined or echo-prone spaces, or if noise limits are part of your site's safety rules.

Key Features of the RH 658 LS

• Built-in silencer — Reduces noise levels by up to 50% versus the RH 658 5L, helping protect operator hearing over long shifts and making it a better fit for noise-sensitive or confined work areas.
• Light and easy to move — At 25 kg, the RH 658 LS can be repositioned often on site without tiring the operator.
• Same shank size as the RH 658 5L — Both use a 22 x 108 mm shank, so drill steels, bits, and other required accessories are easily available world wide as 22 x 108 mm is a standard size all over the world.
• Works across many job types — Suitable for blast hole drilling, shaft sinking, bench mining, quarry drilling, excavation work, and road construction.

Why Choose the RH 658 LS

If noise and vibration aren't a major concern on your site, the RH 658 5L does the same job at a slightly lower weight. But if your operators are working long shifts, drilling in enclosed or echo-heavy spaces, or your site enforces noise exposure limits, the RH 658 LS is the better choice — same drilling performance, with real comfort and safety benefits built in.

Operator comfort has a direct link to productivity. A drill that's quieter and easier on the hands means less fatigue late in a shift, fewer breaks needed to recover from vibration exposure, and better long-term health outcomes for your drilling crew — all of which matter on a busy production site.
