Boring heads are typically broken down by whether they are designed for rough or finish. For longer-reach applications, there’s the choice between a solid boring bar and damping bars for added vibration resistance. From digital heads to twin cutters and modular components, there is a variety of boring tooling available to improve hole-making operations.

For turning toolholders, as for indexable inserts, there is a similar ISO designation system. The system is designed so that each important feature and ...

We assist with product, account and procedure questions. We design tool set-ups, schedule service calls and help our customers receive the maximum efficiency from our tooling.

Sherline offers two sets of six double-ended cutters. Both sets include sizes 1/8″, 5/32″, 3/16″, 1/4″, 5/16″ and 3/8″. (Remember, when cutting in a pocket, the corner radius left by your cutter will be half the cutter diameter.) P/N 7400 is made up of 2-flute cutters, while 7401 offers 4-flute cutters. The 2-flute cutters are recommended for softer materials like aluminum where they are less likely  to become clogged. For cutting tougher metals like steel, 4-flute cutters are a good choice. Each set comes with a wooden block to protect and store your cutters.

Of all the end mills available to machinists, by far the most popular are those with a 3/8″ shank. Because they are made and sold in great quantities, they are an economical alternative to the smaller but less often used miniature series end mills. They also offer the advantage of being double-ended, so you get twice the cutter for your money. Each has a flat on the side against which the set screw of the end mill holder is tightened to hold it in place.

At Sherline, we manufacture the world's most complete line of precision milling machines, lathes, and chucker lathes (also known as Mini or Micro Mills and Lathes). We manufacture both manual and CNC machines for benchtop or tabletop-size workspaces, along with a full line of accessories to support these machines.

Our machines are small in size, but they are capable of making precision parts out of steel, aluminum, brass, or softer materials such as wood and plastic. All of our products are made in the USA. These machines are perfect for light-industrial and home-shop use.

The BIG KAISER modular CK boring system is fully compatible with all machine tool interfaces. The system is made up of more than 150 shank types, reductions and extensions, solid bars, damping bars, ER collet adapters and coolant inducers.

Our advice is to always use the shortest tool possible. Less distance between the part and the spindle is always better. Fewer components are always better too. That’s where a modular arrangement like the BIG KAISER CK precision system shows its value as the world’s most versatile tooling system.

CAUTION: Unlike a drill bit that looks similar, end mills are sharpened on the edges as well as the tip. These sharp edges demand a lot of respect when being handled and used! Also, to keep them sharp, store them in the block provided or individually protected in your toolbox.

The precision and ruggedness of BIG KAISER modular CNC boring tools deliver measurable performance advantages—significantly reducing costs and cycle times. The modular CK system is the best solution for drilling, rough boring, finish boring, milling and tapping. Modular boring tools provide flexibility to assemble the perfect setup for almost any application.

The value of a modular boring system is in its versatility. No matter the work you do, you’ll surely find the solution that fits. Every boring assembly should be kept as short as possible and components should be limited to four or five, not including boring head insert holders.
