INGCO RH10506 rotary hammer review: 4.5J at 1100rpm

The INGCO RH10506 delivers 4.5 J at an unusually quick 1100 rpm for around ₱5,000. Its concrete ceiling is the surprise.

How much hammer is it?

1050 W, 4.5 J, 1100 rpm, 3800 bpm, drilling to 26 mm in concrete, 13 mm in steel, and 40 mm in wood through an SDS Plus chuck.

That 4.5 J is nearly double what the 800 W class delivers, and in hard aggregate concrete the difference is obvious: holes that make a 2.5 J tool labour and heat up go in steadily here.

The pairing with 1100 rpm is what makes it interesting. Most hammers at this impact energy turn at 850 to 930 rpm, because manufacturers slow them to protect bits. Faster rotation clears spoil from the hole between blows, so 10 to 20 mm holes go in quicker than the joule figure alone predicts.

The spec that does not follow

Here is the oddity: 26 mm in concrete, exactly the same ceiling as the 800 W tools delivering 2.5 J.

Impact energy and maximum hole size are set by different things. Joules decide how hard each blow lands; maximum diameter is limited by the chuck, gearing, and how much torque the tool can hold when a large bit binds. So the RH10506 hits hard within a modest hole size.

The practical translation: the extra impact energy buys you speed and confidence in hard concrete, not bigger anchors. If you needed 32 mm for rebar dowels, this does not get you there despite the impressive joule figure.

What comes with it

3 drills, 2 chisels, grease, oil, and a wrench.

The grease and oil deserve a mention. Rotary hammer gearboxes need periodic regreasing and the manual asks for it, but most tools leave you to source the grease yourself, so most people never do it. Including a tube, an oil bottle, and the wrench to open the housing means the first service costs nothing and is far more likely to actually happen.

No spare carbon brushes, which other hammers in the same range do include, and no anti-vibration system, which tells at 4.5 J over a long session.

Is it sulit?

Around ₱5,000 as of August 16, 2026. Check the latest price on Shopee.

Good, but not the best here, and the comparison is uncomfortable. The Tolsen 88531 delivers 5.5 J and 32 mm in concrete for less money, beating this on both headline numbers with a hard case included.

What the RH10506 keeps is the rotation speed, the service consumables, and INGCO’s Philippine parts network. Those are real, and for someone drilling a lot of mid-size holes in hard concrete the speed advantage is genuine. But if you are choosing on capability per peso, the Tolsen is the answer.

Who should buy it

Buy this if you drill a lot of 10 to 20 mm holes in hard concrete and value speed over maximum hole size, or if INGCO local support is what you are buying. If you want the most hammer per peso, look at the 1500 W tools. See how the category ranks in our best rotary hammers in the Philippines roundup, or browse more on our Home Improvement page. Our rotary hammer buying guide explains why joules and hole size are separate specs.

Alternatives to consider

The Tolsen 88531 gives you more impact energy and a larger concrete capacity for less money, with a hard case. For lighter household work the INGCO RGH9028 at 2.5 J shares the same 26 mm ceiling, costs less, and includes spare carbon brushes.
