Preferred angle on a v-groove cutter

I bought 90 degree double angle cutter from Wholesale Tool http://www.wttool.com/product-exec/product_id/29381/nm/Double_Angle_Cutters and after giving it a trial run, I noticed that the point pockets weren't a true 90 degrees, more like 88-89. I have no way to measure it precisely other than putting a square in the pocket and on the cutter blade. The attached photos show the discrepency. My first thought was to return the cutter but I have heard that some cue makers prefer a cutter slightly under 90 degrees for a tighter fitting pocket. What angles are other cue makers using?

While on the topic, when do other cue makers cut the point grooves in their forearms? In other words, how much over fiunished size?

Thanks for the replies

Alex

most issues when doing point work are the veneers it looks like your cutter is the problem first check that then do as you did a test piece
despite what anyone might say the cutter is the most important thing there is only one cutter in my opion that works perfect are you using a mill to cut your points? if you have time call me and ill give you a few tips via the phone...lee

That looks like a low end high speed steel milling bit. I suggest getting a one inch carbide 90 degree cutter. 2 flute cutters will work fine, even in a mill. You might have to take smaller passes but the results are worth the extra time. The bit like I am talking about sells for $50 on my site. I think a few others suppliers sell them also.

I agree the cutter is the most important part in making v points. My advice, from experience, is to buy American. You can have the cutter reground if it is not perfectly true 90* double angle, and the points must be razor sharp. The smaller the shank on your cutter will require smaller passes, or the shank can bend and not run true. I start with 1.2" @ 12" on my fronts and anywhere from 1.3* to 2* angle.
 
Alex's cutter has a 7/8" shank, so I doubt it's an issue with a bent shank.

I have the same cutter and checked mine, and it's dead on. It has also been reground and sharpened though, so it could have been off when it was new. Mine is do for a sharpening again, so he's going to drop his off and get it fixed.

WOW, They can do that? :cool:, :rolleyes:, :grin:
 
Alex, clean your cutter so it looks like new, the gum build up will change the angle. plus cleaning it will cut smoother and run cooler. dont remove the cutter from the machine just put some thinner in a cup and shim up with a block of wood. if it doesnt work try regrinding Jeff

90 ? degree cutter

If you buy a side milling cutter. it should taken to a machine shop and analyzed to make sure it is true. if not you should have it ground to the right specs . ask leon sly . his cutter was 45 one and 48 the other. once he took it and had it ground right everthing fit right.
best regards

The answer seems to be to buy American. A member was kind enough to offer to have my bit re-ground to a true 90 degrees. Thanks for the replies and phone calls.
