deep drilling tool needed

[Buddy Swanson]

I am looking for an insertable drill to cut .531 to a depth of over 4.600. I can only find a insertable spade drill, but I have used them before, and I don't think it will be rigid enough. I am only cutting t-6 alum. but I want (need) speed.

Any help would be great!

p.s. my company is cheap as hell when it comes to spending the $$, so having one made is out of the question.

Buddy, If you have the spindle speed capability to use them, some version of gun drill should do the job. I cut similar holes in one pass 10" deep 40 years ago. You can use a "speeder" such as sold by BIG which also introduces coolant thru the spindle at high pressure to flush out chips. This set-up works fine on ductile iron also. DZASTR

Bijur makes a nice product but realy 4.6" isn't all that deep hss drill with a high speed peck cycle would do it, OR you can try Iscar's chamdrill line.

The iscar chamdrill line only goes to 8X dia. That only gets me to 4.25 deep. Other then that, the chamdrill is what I am looking for.

Thanks

Can I ask, why are you limiting yourself to Insert Tooling?

Seco Carboloy has a new line of insert type and insert spade drills. You may want to check out their website www.carboloy.com

OSG and Titex both offer carbide, coolant fed, deep hole drills up 30XD. If you have a high RPM spindle with good through the spindle coolant pressure, these things can really fly.
