
1. Duringanyworkonnon‐horizontalcomponents,themachinemustalwaysbesecuredwiththe
suppliedsafetychain.

2. Themagneticdrillingmachinemayonlybeusedonaflatandcleansurface.

3. Ifthemachineortheleadshowssignsofdamage,themagneticdrillingmachinemustbeswitched
offimmediately.

4. Wearingsafetyglasses,hearingprotectionandprotectiveclothingisnecessary.

5. Donotwearanylooseclothingorjewelrythatmaygetentangledinthemovingpartsofthe
magneticdrillingmachine.

6. UseonlyaccessoriesorpartsthatarerecommendedbyRotec.

7. Duringdrilloperations,theholecuttermustbecooledandlubricatedwithgoodqualitycuttingor
lubricationoil.

8. Themotormustbeswitchedoffwhentighteningthemachinewiththesafetychain.

9. Whenchangingaholecutter,themagneticdrillingmachinemustbedisconnectedfrompower
supply.

10. Cleantheareaaroundthemachineregularly.Keepthebottomofthemagnetcleananddry.



TheMagneticbase
Materialofminimum10mmthicknessisrequiredforthemagnettoworkthebest.

Theattachmentforcegeneratedbythemagnetdependsonvariousfactors.
‐Thicknessofthematerialthemagnetisplacedon
‐Paintorcoatingofthematerialthemagnetisplacedon.
‐Metalchips,oilorotherdirtunderthemagnet.

IftheLEDindicatorlightsupGREEN,themagnetisgeneratingsufficientattachmentforce.IftheLED
indicatorlightsupRED,themagnetmaynotgeneratingsufficientattachmentforce.

Wewouldliketopointoutthatthisisonlyanindicationandnotacertainlythatthemagnetwillnot
releasefromthematerial.Rotecacceptsnoliabilityensuringfromthemagnetindicatornotfunctioning
orfunctioningpoorly.

Makesurethatthemagnetattachestightlytotheworkpiecebeforeturningonthemotorunitofthe
magneticdrillingmachine.Rotecmagnetshave2coils;makesurethatbothcoilsareincontactwiththe
material.Donotconnectanyothermachinestotheelectricaloutletthemagneticdrillingmachineis
pluggedinto,asitmayresultinthelossofmagneticforce.Alwaysusethesafetychainincluded.Drilling
aboveyourheadisextremelydangerousandisnotrecommended.Fortheuseofmagneticdrilling
machinesonpipes,not‐flatornon‐magneticmaterials,werefertoourbrochureorourwebsite

!!!IMPORTANT!!!

Drilling
Nowthatyouhavereadtheexplanatoryinformationandsafetyrecommendationsabove,youarereadyto
actuallystartdrilling.Followthese10stepsforbestdrillingresult:


9

1Usethetipofthepilotpintodeterminethecenteroftheholetobedrilled.
2Turnthemagnetonandverifythatthedrillisintherightpositionandthatthemachineis  
pushedtightagainsttheworkpiece.`
3Ifyourmachineisequippedwithaautocoolantsystem,putopenthevalvetoreleasetheoil.
Ifyourmachinedoesnothaveaautocoolantsystem,filltheholesofthespindlewithoil.
4Turnthemotoronatthehighestsettingandallowittorunatfullspeed.
5Turnthearmstostartdrilling.Applyonlyaslightpressurewhentheholecuttertouchthe  
metal.Donotpushtheholecutterwithforceintothemetal.
6Applyaregularpressurewhiledrilling.Thedrillingperformancedoesnotimprovebyputting 
morepressureonthetool.Toomuchpressurewilloverloadthemotorandyourholecutter  
willbewornsooner.Letthecutterdothejobandgiveittimetocutthemetal!!!
7Adjusttheoilsupplywhennecessary,ifyourdrilldoesnothaveaautocoolantsystem,stop  
drillingregularly,refilltheholesofthespindleandcontinuedrilling.
8Applylesspressurewhenthedrillcutsthroughthematerial.
9Turnthearmstoputthemotorinhighestpositionandturnoffthemotorunit.
10Removetheburr,metalchipsandcleanthecutterandsurfacewithoutgettinginjuries.   
Caution:Themetalpiecedrilledoutcanbesharpandveryhot!!

TheRTC.50‐Thavea2‐speedgearboxandaelectronicspeedadjustment.Topreventheatbuild‐upalwaystryto
keeptheelectronicspeedadjustmentashighaspossible.Usetheuppergear(high)forholecuttersupto20mm
andthelowergearforholecuttersabove20mm.TheRTC.50‐Thaveafullyelectronicmotorunitwhichmeasuresits
speedcontinuouslytohavethemaximumpoweravailable.WhenyoustartdrillingtheRPMcangodownfora
momentuntilthemachineitselfwillincreasetheRPM.Thisiscompletelynormal.

Toselectanothergear,turnoffthemotorunitandthemainpower.Pushtheblackswitchonthesideofthegearbox
andslideittotheotherposition.Aslightturnoftheoutputshaftbyhandwhileslidingtheblackswitchtotheother
position,canbenecessarytolineupthegearsinside.Proofthatthegearislockediftheblackswitchcomesbackto
front.

Tapping50T
Drilltheholeontherecommendedsizeofthetap.Donotturnthemagnetofftokeepthemachineonitsposition.
Takethecutteroutanduseatapcollettofixthetaptothemachine.TheseadaptersexistinseveralDINandISO
normsandarebasedontheshaftdiameterofthetapthatisused.Usethelowgearandlowrpmfortapping.Stop
themachinemanuallybeforethetapiscompletelythroughthehole.SelecttheReverse(Left)andletthetaprun
backslowlybutalsosupporttherunbackbyturningbackthehandles.Donotletyourtappushbackthemotorunit
byitself!Ifyourtaphavetomakethewholewaythroughthematerial,thenremovethetapoutofthecolletwhen
theholeiscompletelytapped.
!!!IMPORTANT!!!
Whenusingyourmagneticdrillingmachinenon‐horizontalorupside‐downbeaware
thatnooil,drillingcompoundormetalchipscanfallintothemotorunit.
