Reduced shank drill bits > 25mm

Anyone have some old, unloved reduced shank drill bits lying around.

Looking for BIG ones, over 1 inch / 25mm.

Specifically looking for something in the 32, 33mm range

Happy to sharpen it and send it back if required :thumbsup:

Step drill not an option for the operation I want to do.

My tailstock is Morse 2, so anything in M2 around 32/33mm would work as well. Largest morse taper drill bit I have is 20mm

Got a set from 14 to 25mm already, was looking for a single large diameter one, all good.

I was perusing the 'sale' table at the back of a tool shed style shop in Rotorua last year. Wooden box with about 30 morse taper bits in it, all rusty, in sizes from 10mm to 32mm.
"What da ya want for the box of rusty bits??" says me cheekily..."Oh, how about $50 cash?"

DONE!!!:ORLY:

Think I damaged the sides of me wallet whipping the $50 note out :o

Pays to be a bit careful with reduced shank drills....dont use a precision chuck or hand chuck......the torque going threw it will either tighten it ridiculously (hand chuck) requiring nasty tools to undo or slip and damge jaws and shank of keyed chuck.

I am sure you will be gentle just something to be aware of and dont use your best chuck.

@ DavidGunn, just checked the postbox - it arrived today :thumbsup:
@veitnamcam, noted. this one is a Morse 2 taper, so will go directly into the tailstock, but I will use lots of cutting fluid - gummy aluminum.
