  • Boring Bar Set, Carbide 3/8" Shank $15.95
  • Knurls, Fine Diamond $5.49
  • Dial Test Indicator, 0-15-0 x 0.0005" $29.95
  • Small Hole Gage Set, 4-Piece $12.95
  • Dovetail Cutter, 60° 3/4" Diameter $14.95>
  • Cutting Fluid, Re-Li-On 4oz $3.95>
  • Thin Parallels, 3" Long 4 Pairs $14.95


Boring Bar Set

Boring bars allows to work internal holes in the lathe or the mill.


This set has high endurance carbide tips. The dirty grease is to protect the shafts, that needs to fit fairly tight in the lathe or mill support.

Knurls

Mounted in a tool like scissors (there are other types), they make these pretty tiny rhombus finish some round handtools have.


Dial test indicator

This nice tool allows you to measure small deviations using a tiny ball end tip. A common use is to center the head of the mill to a piece with an already done hole, to enlarge or finish it.


Although cheap, doesn’t look bad. I wish to get a mitutoyo some day.

Small Hole Gage Set

This tools provide you a cheap method for measuring internal diameters. They has an expanding head, so you can copy the size of a hole an then measure it with a micrometer.


Well, I have to say that quality of this item is not very good. To be usable, I was to spend a couple hours with a file and sand paper (even one of the tips gets stuck). But for 13 bucks, you get what you pay for.

Dovetail Cutter

This type of end mill is used to cut these common”V” ways.


Tough it looks a bit rough, you will not find any cheaper, and looks great for occasional work.

Cutting Fluid

I usually use current oil (sometimes), but for harder materials a good cutting fluid would be a great help.

Thin Parallels

In pairs, these are usually used to rise a piece keeping parallelism to the base surface.


I took measures of every pair at two sides. This is the result:

A B Nominal
7/8″ 22.230-22.234 22.230-22.229 22,225
3/4″ 19.051-19.052 19.054-19.055 19,050
5/8″ 15.888-15.881 15.880-15.879 15,875
1/2″ 12.705-12.705 12.703-12.703 12,700

Not bad (parallelism is more important than nominal accuracy). The other sides are not very flat, but these are not supposed to be used. My only complaint: some box or bag would be great, as this type of tools must be handled and stored carefully (please note that my mic has 0.01 mm reading; the last digit was approximated by eye).OverallAll these are cheap tools, but fulfills in more or less grade the desired function. High quality tools will cost several times this ones; for example, a mitutoyo dial indicator will easily cost more than this whole pack. Also, as widely know, more importantly than the tool itself is how you use them.
