Jason LaPort Posted September 18, 2013 Report Share Posted September 18, 2013 I just bought a 1983 Skil Roto Hammer and I'm wondering what I'm in for. I'd like to know where I can get a manual for it and whats most likely going to need maintenance first before I fire it up. This is the biggest drill I've ever bought and its advertised in good running order but I wont be able to see for myself until it gets here. Also any info on where to get parts and bits would be sweet. I'm a hard rock miner and I plan on abusing this thing a little bit so the more info the better. I'm thinking about going with a drilling steel and replaceable tips. What can I do to get my drilling speed through the rock faster with my vintage toy? Thank for any help and advise.

Conductor562 Posted September 18, 2013 Report Share Posted September 18, 2013 Maintenance all depends on the drill and it's condition. It undoubtedly could stand to be opened up, have the dust blown out, and lubed up good.Replacement parts may be tricky. eReplacement parts usually has damn near every part known to man, but this is a 30 year old drill we're talking about.As for the manual, I'd email Skil customer service to start. They should either have one, or know where to tell you to look.Do you have a Bosch service center in your area? 1 Quote Link to comment Share on other sites More sharing options...
Jason LaPort Posted September 19, 2013 Author Report Share Posted September 19, 2013 I dont think I have a Bosch service center close by. I can buy Bosch from my local home depot but they dont service them. Quote Link to comment Share on other sites More sharing options...
DR99 Posted September 19, 2013 Report Share Posted September 19, 2013 I don't know how much you paid for I hope not too much, but Skil for the most part has been relegated as a value brand by Bosch. Like conductor mentioned parts might be hard to find with it being that old the plus side its probably spline drive so you can still get bits for it. I'm not the biggest rotohammer expert,but you should be able to find bits at most places online. For a manual try searching the model number some one might have scanned it and put in on the internet, or like hit up customer support like conductor also mentioned. 2 Quote Link to comment Share on other sites More sharing options...
Jason LaPort Posted September 22, 2013 Author Report Share Posted September 22, 2013 Got it in the mail today. Its not even close to being pretty by any means. I'm definitely gonna clean this as best I can inside and out before I even think about firing it up. I keep hearing the word spline drive, still not sure what thats referring to. I'll try to get it all cleaned up tomorrow and see what she sounds like. Thanx for the advice guys. Quote Link to comment Share on other sites More sharing options...
DR99 Posted September 22, 2013 Report Share Posted September 22, 2013 Spline drive refers to how the bit attaches to the chuck most rotohammers use SDS bits now. Spline is used on the bigger demolition hammers and such. Quote Link to comment Share on other sites More sharing options...
Jason LaPort Posted September 23, 2013 Author Report Share Posted September 23, 2013 Thanx for the info. I got it cleaned up on the outside but still haven't found a parts diagram that makes me comfortable with taking it apart. Looked like it was rolled in grease an battered in the finest saw dust you can find and then sat in a corner of a dirty, dirt floor garage for the last 20 years. I still dont want to start it without cleaning the inside first. Doesn't look like there's any oil in it either so that makes me wonder just a little bit too.

Conductor562 Posted September 24, 2013 Report Share Posted September 24, 2013 Compressed air will blow most of it out. The rest you can use CRC QD Electric cleaner or similar. 1 Quote Link to comment Share on other sites More sharing options...
Jason LaPort Posted October 3, 2013 Author Report Share Posted October 3, 2013 I can't seem to find an adapter. From what I've found online it looks like I have a 7/16" hex bit and I'm hoping to find a 7/16" hex to sds adapter. An ideas where I can find one or if they even make them?

Jason LaPort Posted October 4, 2013 Author Report Share Posted October 4, 2013 http://www.ebay.com/itm/SKIL-HEAVY-DUTY-ROTO-HAMMER-DRILL-726-TYPE-8-5-5-AMP-WITH-STORAGE-BOX-AND-MORE-/310744553095?_trksid=p2047675.l2557&ssPageName=STRK%3AMEWNX%3AIT&nma=true&si=5%252BQLEHeUwcdMs21kNbhQY9PCFeU%253D&orig_cvip=true&rt=nc This is the drill that I bought. In one of the pics you can see the shape of the bit is different. It has a narrow part in the bit where a spring clamps onto the bit. I need an adapter with that narrow spot in the bit. Its Hex to SDS that I need but I'm not sure if they make one for my dinosaur of a machine. Quote Link to comment Share on other sites More sharing options...
RedSionnach Posted October 4, 2013 Report Share Posted October 4, 2013 Also found this one. No picture nor good description. You could call them for the info.Part number P-SDS. http://www.buydrillbits.com/products/specials.php 1 Quote Link to comment Share on other sites More sharing options...
Jason LaPort Posted October 4, 2013 Author Report Share Posted October 4, 2013 That's the closest I've seen but thats a spline bit not a hex. I'll probably be making a few phone calls tomorrow. Thank for the help man. Quote Link to comment Share on other sites More sharing options...
RedSionnach Posted October 4, 2013 Report Share Posted October 4, 2013 I think you looked at the PB-SDS. The P-SDS description says.... SDS ADAPTER FOR MILWAUKEE AND SKIL 7/16 HEX TOOL.5300 AND 726 SERIES 1 Quote Link to comment Share on other sites More sharing options...
Jason LaPort Posted October 4, 2013 Author Report Share Posted October 4, 2013 Yup I did. I didnt see it last time and thought you meant the PB SDS. Ok so its a pretty penny but with that I could get bits from the local store instead of shopping online. Thanx man. I'll bookmark that page until I get a few more dollars. Should be in a week or so. Thats awesome!! Quote Link to comment Share on other sites More sharing options...
RedSionnach Posted October 5, 2013 Report Share Posted October 5, 2013 Not a problem. Glad to help. 1 Quote Link to comment Share on other sites More sharing options...
Jason LaPort Posted October 8, 2013 Author Report Share Posted October 8, 2013 Well I guess I dont need the adapter now. Less then 2 hours drill time and the drill is dead. Now I'm completely drilless. Quote Link to comment Share on other sites More sharing options...

Jason LaPort Posted October 11, 2013 Author Report Share Posted October 11, 2013 WooHooo back to my boring ol' self tomorrow. The Skil is still alive. The plug in was falling apart. My buddy gave the one prong a little tug and pulled it right out. He checked the brushes, changed the plug and it fired right up. Just as loud as the last time I ran it so hopefully tomorrow is game on until I get my new drill and trade in my other one. I'll have 3 drills within a week to hold me until I save for my hilti 1 Quote Link to comment Share on other sites More sharing options...
