Marcrist ddm2

[tamz]

i'm interested to see which is the better beast between the ddm3 and milwaukee.

It is a no contest if you put the ddm3 on speed 3

Not that i've ever felt. I can hold it with one hand and drink my coffee with the other :smile:
It's easily held but i'm about a foot taller than you and probably a wee bit stronger.

 

[Killy Bing]

taller yes but as for strength i'm pretty good usually !!! I got attacked when I was 14 by a group of 20 ish year old showing off , knocked to the floor and one of them jumped up both feet onto my right hand. I have to look after it now and when a core drill snatches man do I feel it !!! hence why I like the milwaukee

 

[tamz]

Use your left hand them. You need to learn to be ambidextrous and never be afraid of the tool you are using. Thats when it will bite you.
You can hold it no problem and it never snatches.

 

[Killy Bing]

I do, its just that occasion you can't get into the right position thanks tamz, i'll consider the ddm3 then

[mcniven]

do others agree if so il order one, will it be as good???

 

[Dannypipe]

I'll let you know. I've ordered mine!

 

[g60rge]

ordered the bbk2 for 206 pounds delivered - let you know how good it is, no doubt screwfix will start selling these.

 

[g60rge]

wow,

so last week i drilled a hole for the stack pipe with my dewalt hammer drill, got through the breeze block ok, then it wouldnt drill through the brick, i gave up and stitch drilled in the end, time taken 45mins. dead arms and shoulder pain for 4 days, (bare in mind ive had double shoulder operations)

today i drilled the boiler flue hole with the same worn drill bit with the new sparky drill, woooooow, it took 2 mins, arms are fine!!!!

one of the if not best investments soo far after the power flush machine!

the sparky re brand is definitely the real deal

 

[gasmanrob]

Sweet!

Err anyone wanna buy my hardly used ddm1?

 

[Dannypipe]

George - I found the gear on mine hard to change. I have the three speed one. You have to manually shift the chuck and slot it into gear. There is info in the Sparky instructions about this. I hope we haven't damaged the gear box because we actually span the drill out of gear at the start and then when the motor slowed, we slotted it into gear. What do you think? Tamz you have used these???

Its not the same as a DDM1 which is a totally different drill. This is a total beast of a drill compared to the DDM1.

Sparky BBK21500 2 Speed Core Drilling Machine 1500 Watt 110 Volt - Sparky from Cassells Industrial Products Ltd UK

being as the other company is out of stock !!

 

[tamz]

It looks the same gun as the old DDM2/3 Danny.
Probably made by the same company. There are a few similar machines under different brands (do an image search for handheld core drill).
You have to (usually) move the chuck to change gears. This is common on a lot of tools.
I just leave mine in speed 3 for everything unless i need more torque on a particularly deep hole (the clutch kicks in more on higher speeds).

 

[lame plumber]

tamz is the 3 speed better than the 2 speed as it looks like the top end speed is the same for both at 950 cheers jcd

 

[tamz]

Speed 3 on a ddm3 is >3000rpm, speed 2 around 1800.

Speed 2 on a ddm2 is >2000rpm

 

[lame plumber]

more speed means quicker holes

just managed to read the small print on the ddm3 sparky,
No Load Speed: 950/2,100/4,300/min. so I might save the other £100 for that one

 

[tamz]

more speed means quicker holes

Usually but depending what you are drilling it sometimes glazes the tips if you are dry drilling.
Run the core in a bit sandstone to deglaze and sharpen it again.

I paid around £250 for my ddm2 and £4 odds for the ddm3 so these ones are a lot cheaper.

Hi Guys,
Cant seem to find anywhere to buy the marcrist ddm3. Not keen on the sparky version. I have done a quick google for others and come up with the rems picus s3 REMS Picus S3 - Electric diamond core drilling machine thoughts?
