Powerhouse PHB-RH-32D rotary hammer review: 6J SDS Plus

The Powerhouse PHB-RH-32D range delivers up to 6 J and 32 mm in concrete through the cheap SDS Plus chuck, for around ₱4,900. The catch is that one listing covers two different tools.

How much hammer is it?

The listing covers two variants:

• PHB-RH-32D: 1200 W, 0-800 rpm, 32 mm in concrete.
• PHB-RH32DX: 1600 W, 200-900 rpm, 4350 bpm, 6 J, 32 mm in concrete.

Six joules through an SDS Plus chuck is the interesting part. Most SDS Plus tools stop around 5.5 J because the 10 mm shank limits what it can transmit without destroying bits. Getting 6 J means near-SDS-Max hitting power on bits that cost a fraction as much and are stocked everywhere.

Both are rated 220 V at 60 Hz, matching Philippine mains rather than carrying a 50 Hz European spec sheet.

The two-variant problem

Powerhouse publishes the 6 J impact energy and the 4350 bpm figure for the 32DX only. For the 1200 W PHB-RH-32D, neither is stated.

That is a real gap. Impact energy is the spec that decides how fast a hole goes in, and on the cheaper variant you simply cannot find out what it is. Neither variant publishes steel or wood capacities either.

So the practical advice is: establish which variant the listed price buys before you pay. If it is the 32DX, you are getting one of the hardest-hitting SDS Plus tools available. If it is the 1200 W version, you are buying partly blind.

Is it sulit?

Around ₱4,900 as of August 16, 2026. Check the latest price on Shopee.

If the price buys the 32DX, this is excellent value: 6 J and 32 mm in concrete for the same money as tools delivering 5.5 J, with a case included, from a brand with a Philippine flagship store behind it.

If it buys the 1200 W variant, the comparison is murkier, and the Tolsen 88531 at a published 5.5 J and 32 mm becomes the safer choice simply because you know what you are getting.

There is also no anti-vibration system stated, which tells on a 6 J tool over a long session.

Who should buy it

Buy this if you want maximum SDS Plus hitting power without moving to expensive SDS Max bits, and you are willing to confirm the variant with the seller first.

Alternatives to consider

The Tolsen 88531 publishes 5.5 J and 32 mm with no variant ambiguity, and includes a hard case and a fuller accessory kit. If you need genuine breaking power, the Powerhouse PHB-RH-40D steps up to 10 J and 40 mm through an SDS Max chuck.
