I would like to say that it doesn't really drive the bit back and forth it actually hammers on the end of the drill bit. There is a steel piston inside the gearbox which rapidly thrusts up and down and on every downward stroke it impacts on the striker pin, which then transfers that energy to the drill bit. The drill bit then transfers that energy to the material. Since all parts involved are hardened steel no energy is lost. The piston and striker pin especially are made from extremely durable steel.
At the :53 second mark you say "It comes with 3 modes" but if you look, there are actually 4 modes. What's that other mode that you ignored right next to the hammer only mode? What does it do?
Hi. The setting between the ‘Hammer Only’ and ‘Rotary Hammer’ is only used while the device is at a standstill. It allows the chuck to move freely, enabling the repositioning of a retained SDS breaker steel to a desired working angle. Thanks.
@@jontnoneya3404keep in mind, that setting depends on the manufacturer. Mine has the 3 modes but no function to turn the bit like this one has, I have to use the rotary/drill option to do it instead. Handy feature this.
What is the purpose of the different size such as 1 inch or 5/8 rotary hammer drills? Obviously u can put in bigger bits in the larger one, but can the large also accommodate smaller sizes?
You can fit whatever size SDS+ bits into any SDS+ drill. Likewise for SDS MAX. But bigger drills will be faster and have more power to do bigger jobs, such as drill bigger sized holes or hack masonry faster compared to a smaller drill
The drill bits have three dimensions listed on Amazon. I've been searching for an explanation of what these three dimensions represent but haven't had any luck after 20 minutes of looking.
Hi. The SDS Drill Bits on our Amazon store front should either have the product dimensions or the packaging dimensions displayed in the 'Technical Details' table. Thanks for highlighting this, as we've noticed a few with errors that need to be rectified.
Hi. It really is impossible to specify a run time as there are so many variables, such as the material to be drilled into, the depth, the diameter, and also the settings being used on the drill (rotary or rotary with hammer). Also, with any electric powered tool on the market, the motor will of course heat up with prolonged use. However, with the type of work SDS hammer drills will be used for, regular breaks should be taken anyway to help prevent any hand-arm vibration damage that could occur. Thanks.
Great question, I try to use “common scenarios” to give me an idea Some drills are labeled “Professional Use” for those I imagine some 10 minutes of non stop then some 3 or 5 minutes break (as if I were installing a big TV over a concrete wall. For “Industrial Use” I imagine more serious and continuous work, something like a full day of a group of contractors doing some major installations over concrete, like 8 hr shift of drilling and hammering some 15 min then 3 min break. Like embedding floating closets over concrete for say 4/6 apartments,
@@PippeML Well i can speak for makita sds-rotary hammer. With those you can drill and break concrete for hours without problems, as long as you have batteries or corded.
Hi. If you'd like to give our Technical Dept. a quick call with the model no. they will be happy to advise you. Alternatively you can email them on technical@sealey.co.uk Thanks.

Can this be used for drilling through metal?
Hi. Yes, they are ideal for drilling through tough materials such as masonry, concrete, hardwood, and steel. Thanks.

@@sealeytools The product dimensions have no explanation. What is a 6 in x 4 in x 3 in?
@@The_Savage_Wombatcould it be bit length and usable drilling depth?

My sds has a lever in back of drill by handle. Can you explain 🤔 it to me

Dumb question what does SDS stand for
Hi. It stands for Slotted Drive Shaft. Thanks.
Thanks
