To determine true cost, consider the total life of the drill.
Read MoreRigid Tapping--Sometimes You Need A Little Float
One of the most common methods of tapping in use today on CNC machines is 'rigid tapping' or 'synchronous feed tapping.' A rigid tapping cycle synchronizes the machine spindle rotation and feed to match a specific thread pitch. Since the feed into the hole is synchronized, in theory a solid holder without any tension-compression can be used.

A modular drilling and boring system has changed this oilfield product manufacturer's holemaking operations.
Read MoreDrilling Dry With A Heat Pipe
It's widely known that hole making is, by a significant margin, the most frequently performed process among metalworking operations. It's also among the most difficult operations to control from a thermal perspective.

There are a number of tools available for shop personnel to evaluate the right angle relationship between two surfaces. The basic machinist square has a number of variations, the most common being the hardened steel square used to check right angles and set up milling and drilling machines.
Read MoreA Boring System For Non-Round Holes
Machining an out-of-round bore is easy if you're not particular about the location or magnitude of the roundness error. But accurately machining a hole that has a precisely defined non-round profile is a capability that would seem to be well beyond what a standard boring bar can accomplish.
