Getting slowly caught up Cutting holes in sheet metal is a bear I have the scars to prove Have a Whitney hand punch, hole saws and even a couple of greenlee punches to use I do a lot of work in sheet metal I also have a ring and circle shear I do a lot of sheet metal work Good information Comment from : @feathers352 |

I always thought those steps drills were a gadget too UNTIL I actually used one -- they are quicker and safer Can't tell you how many times i've struggled with making larger holes with conventional drills I was glad at that time my drill press only had a 1/3 HP motor - or I could have had a real bad day brThose other adjustable pivoting death machines sure aren't worth taking the chance with - despite my trying -- all can go well UNTIL it snags - OH BOY brUsing the hole saws - I've found that in soft materials (plastic) to run them in reverse I know everyone will say how it damages the cutter But otherwise in soft material they grab too hard especially using a portable drillbrI also like to use the chassis punches like you mentioned Got a whole series of those from my Dad and he used to make lots of Ham Radio equipment with aluminum chassis Comment from : @RelentlessHomesteading |

Two words brPLASMA CUTTER makes much of the hole saw approach redundant Comment from : @jarredsegal6842 |

@mrpete222brDrilling in aluminium is easy, but what do you do if your sheet metal is made of 1 mm thick steel? Comment from : @OpenGL4ever |
 |
this guy's got SKILZ :) Comment from : @whattomsays3 |
 |
What about a knockout to make holes? I've used them occasionally! Comment from : @trialnterror |
 |
What is the best way to put large holes into thicker material on the mill? For example a 3" hole in 25" aluminum or steel Comment from : @UnWoozie |
 |
Those abominations with the lathe toolbits would work nicely in a blacksmith's post drill but not many shops have those now Comment from : @mclarpet |

I very much enjoy your videos! I have a couple of suggestions for inclusion in future First, since there is nothing more useless than the "keyless" chucks used on most portable drills today, how about some words about how to remove a chuck so it can be replaced? Second, some info on how to properly tighten a Jacobs chuck using all three key positions to minimize runout Maybe even a demo of measured runout using only one position on the chuck, versus drawing the jaws up evenly, by using the holes in rotation Thanks LADye Comment from : @larrydye3948 |

it may not grab, but it will pull you off center (very slowly, but worth noting) Comment from : @Tjousk |

Tom at the OxToolCo channel showed use of rotabroaches for making holes in thin sheet Worked great, with no burrs They also work in thicker metal brbrFor production uses there's also laser, plasma, and water jet machines that do quick and accurate work, but those aren't practical for home use unless you have a lot of money and space Comment from : @BigMjolnir |
 |
I learned most of these tips the hard way lol Comment from : @johnfranks |
 |
Those trepanning tools you showed to us, they can be safely used in your bridgeport ive done it and they are very effective !! I:) Comment from : @StuHo1mez |

Great video as always When using the craftsman type saw ( dont know what its name is, jigsaw?) Make sure you got the proper type of theet orientation on the blade The blades for metal only cuts on the upward stroke unlike blades for wood etc If you dont it will jump around like crazy:) Comment from : @Henta88 |
 |
As always, thanks’ for taking the time to make this video! And I support this site M Comment from : @mikeadrover5173 |

In the workshop of the company I made my apprenticeship at they had a hold down attached to the drill press table to hold the sheet metal in place while drillingbrI found that this is a really great feature when you use a normal drill bitbrIt had a quick release mechanism as well and we all used this a lotbrI'm actually surprised that you don't have one of thesebrI used it for drill bits to up to 30mm (over 1") Comment from : @mikkosha |
 |
One of my favorite ways to cut holes in sheet metal is to use "Brad point" drill bits They make a clean hole with little or no burrs Good information!, thanks for sharing! Comment from : @LikeToMakeTools |
 |
On hole saws, make sure you get the right sort for the materialbrbrI tried cutting steel with just a regular cheapo hole saw Lot of noise, heat, but not much cutting Comment from : @BigAdam2050 |
