Corner rounding endmills are used to add a specific radius or to remove sharp edges and burrs. RedLine Tools offers carbide corner rounding tools in both uncoated with AlTiN coating. Our selection of carbide corner rounding endmills contains radius sizes ranging from .0100 to .3750. All RedLine Tools corner radius tools are proudly made in the USA.

Thread mills are versatile substitutes for taps and have several advantages. They have the ability for one tool to make several different types of threads. They are made from carbide and can be used in high speed machines. A single profile thread mill can also be used to chamfer edges.

Carbide rotary burs are used for cutting, shaping, and grinding materials in a process called deburring. They are versatile tools and can be used on many different materials including carbon and stainless steel, cast iron, aluminum, non-ferrous metals, and plastics. They are often used in hand tools and milling machines depending on the application. RedLine Tools offers a wide range of styles of carbide burs for any application.

A reamer is a cylindrical or conical rotary cutting tool used to enlarge and finish holes, to a precise measurement and finish. There are two types of reamers, hand and machine called chucking reamers. All reamers have either straight or helical flutes where chips, cooling and lubricating fluid pass through. RedLine Tools offers a full line of carbide, HSS and cobalt reamers for all of your hole finishing applications.

We receive frequent requests for monolithic tooling balls of single piece construction. This approach may look good on paper but it doesn’t pan out in the real world. Of the many examples of this design that we have inspected we haven’t found one single part, that came close to meeting even commercial tolerances. I had one manufacturer of these parts tell me that it didn’t really matter, because his customers couldn’t even measure the tolerance anyway.

There are many types of drills, each designed to perform in different materials such as steels, cast irons, aluminum, stainless steels, plastics, composites and alloys. Each drilling application has specific requirements from deep holes, pilot holes, micro applications, etc. In the metal cutting industry, CNC drilling uses either milling machines, drilling centers or lathes to produce round holes. RedLine Tools offers a full range of drills for every application including; Micro Spotting, Spotting, Micro Drilling, Stub Length, Jobber Length, Screw Machine Length, Taper Length, Multi-Material, Double-Margin and Combined Countersink Drills. We offer HSS drills for general purpose applications and Cobalt and tungsten carbide drills for production applications which can run faster, last longer and withstand extreme conditions in harder materials and higher temperatures.

RedLine Tools dovetail cutters are manufactured from premium carbide to optimize strength and durability and are proudly made in the USA. Our broad selection includes 5°, 10°, 15°, 20°, 30°, 45°, 60° solid carbide dovetail cutters in uncoated and AlTiN coated.

RedLine Tools carbide keyway cutters can be used in a variety of applications. Our key cutters are available in solid carbide or steel shank with a carbide head. We also offer a selection of uncoated or AlTiN coatings for use in multiple materials. Our selection includes full radius, corner radius, large diameter, long reach, deep slotting and fine tooth. All RedLine Tools key cutting tools are proudly made in the USA.

Need to chamfer a hole or finish an edge? RedLine Tools has an extensive offering of chamfer tools, countersinks, and edge breakers to help you get the job done right the first time. Manufactured from solid tungsten carbide, and available both coated and uncoated, our selection of countersinks, edge breakers and chamfer mills have the hardness and overall durability to remain sharp and effective when high repeatability and output is required.

Carbide bars are used on many different types of applications, most often in Turning Centers and Swiss, however they can also be used in Machining Centers. They are valued for their ability to get into small and tight places and come in several different styles depending on the application. RedLine Tools offers boring bars, grooving bars, threading bars, and profiling bars all of which are made from solid tungsten carbide.

From chamfering to cutting a keyway, there is a specialty tool for nearly any task. RedLine Tools has a large selection to choose from including; dovetail cutters, corner rounding tools, chamfer tools, key cutters, double angle cutters, and engraving tools. Find your specialty tool below.

To meet the almost daily calls, that we get, for custom made tooling and construction balls, we have set up a small department just to produce these items. If you use our parameters, our typical delivery from this new department is two weeks, instead of the previous four to eight weeks. Using our parameters, typically prices are one half to one quarter of the old price structure. We have some strong design suggestions, to keep the cost of tooling balls down and the delivery good. The first choice for the Ball Material, is type 440c, hard stainless steel. This hard stainless steel ball is threaded by electrical discharge machining (EDM). The alternative for the ball material is to use a tungsten carbide sphere that are also threaded by EDM The threaded ball is screwed and glued into a spherical cavity in the hardened tool steel stem or shank, to form the blank for the tooling ball. A typical design, that we receive, from customers will choose a type 440c stainless steel stem or shank, which would be a good design choice, if you were making a hundred pieces or more. To harden type 440c stainless steel requires a very high temperature of 1925 degrees Fahrenheit, in a vacuum or controlled atmosphere furnace, at a typical cost of $125.00 lot, and at least a one week delivery. The stem or shank of the tooling ball is located in a hole during use, and never sees any corrosive environment, so there is really no need for a stainless steel material. By using hardened tool steel, all of the same tolerances can be held as with the 440c construction and this material is actually, harder than the stainless steel.

When engraving, tool selection is critical. RedLine Tools metal engraving tools provide you with an unbelievable selection available in uncoated and AlTiN coated. Our selection of metal engravers include: standard point, spiral flute, chisel style, radius tip, 2 flute, extra-long, fine point, and soft material engraving tools.

Taps are required to make threads for bolts to hold two pieces together. The cutting end of a tap removes material from a hole in the workpiece in the form of chips that are stored either in the flutes or pushed ahead or behind the tool. We offer a full line of taps for every application.

A toolholder is a device that safely provides a critical interface between the cutting tool and the spindle of the CNC machine. The cutting tool is mounted into the holder and is tightened so it does not move or vibrate during machining; providing the stability you need to ensure precision cuts every time. Redline toolholders are all guaranteed to meet or exceed all AT3 shank specifications to ensure a proper fit onto your milling machine spindle. We offer Cat 40, Cat 50 and HSK63A toolholders in: shrink fit holders - ER11 – ER16 – ER20 – ER25 – ER32 – ER40 – TG100 – TG150 collet chuck holders, hydraulic chucks, endmill holders, face mill (shell mill) holders, tap (rigid and tension & compression) holders, Jacobs taper holders, slitting saw holders, stub arbor holders, Morse taper holders, boring head holders, adapters, toolholder packages, and more.

Cutting Tools are one of the most critical components in the manufacturing process. Quality materials, creative designs and tight manufacturing tolerances are critical elements when manufacturing cutting tools. At RedLine Tools we incorporate state of the art design to provide increased performance with longer tool life. With over 29,000 items online, we have what you need in stock for fast delivery. Choose from end mills, drills, taps, thread mills, reamers, carbide bars, and specialty tools like double angle cutters, chamfer and countersinks, key cutters, dovetail cutters, engraving tools, slitting saws, carbide burs and more.
