New here please help

Hey guys, I'm new here and very new to using mill machines so I do apologise if this question sounds stupid but here goes.

My new machine only allows me to drill a maximum of 13mm but I need to drill holes ofvatleast 19mm, is there a workaround by buying a new chuck or something like that? And I'm sorry if this is a stupid question and I hope iv posted this in the right section.

Thank you all in advance

That's brilliant thank you very much

I would run them Screwfix blacksmith drill bits very slowly and lot's of lubricant, they are not the toughest bits, oh and get used to sharpen them on a grinder, or if you are only wanting one size in particular, try buying one quality bit from say Cromwells etc.

Thanks for the reply guys, are these kind of drill bits available where the bottom of the drill bits are flat? I need to cut a flat disk shaped hole that's all and the bottom of the hole must be flat and not domed, if that makes sense lol.cheers again

Hi Richard
A slot drill will give you a flat bottom hole, but RS Components want 61.45 Plus VAT and you will need a holder for it as well. you don't mention what material you are wanting to use it on ?

Hi, I'm using it on stabilized wood so I'm not wanting anything that will cut through thick steel. Thank you

What size holes are you wanting to make? If it's not too big, use a end mill to mill a flat hole, a drill bit flute is designed to cut and draw away the swarf.

The thing with spade bits, they have a point so still won't make a perfect flat hole.

Hi Richard
You could try experimenting with the blacksmith drill recommended by greeny but grind it flat bottom, it needs to be fed slowly using a high rpm but this can only be done on a machine with fine feed control on the quill otherwise it could grab and pull itself into the job if you were to use the hand feed.
