Amann Girrbach Titanium Milling Burs

Titanium Milling Burs for Ceramill Metal Milling

Eagle titanium milling burs are tungsten carbide burs with geometries made for metal milling. They are compatible with Amann Girrbach Ceramill milling units that mill metal and are used for titanium and cobalt-chrome (CoCr). Two diameters are available, 1.0 mm and 2.0 mm, so you can replace the detail bur and the roughing bur separately.

What These Burs Are For

• Custom titanium abutments and individual titanium bases
• Screw-retained bars, bridges and frameworks in titanium or CoCr
• Metal framework production in Ceramill metal-milling workflows, in the lab or in a milling center

Sizes and What Each One Does

How to Read the Sizes

The size is the cutting diameter in millimeters. Your Ceramill software assigns each diameter to a tool position in the metal strategy, so a worn 1.0 mm bur is replaced with another 1.0 mm bur, and the same for 2.0 mm. Check the tool list in your software before you order to see which position is close to the end of its tool life.

Why Carbide for Titanium and CoCr

Metal milling needs a sharp, stable cutting edge rather than a grinding surface. Titanium is tough and tends to stick to the edge, and CoCr is hard, so the bur geometry is designed to cut these metals with smooth surfaces and less chatter. Diamond-coated zirconia burs and diamond grinding burs for glass ceramics are not made for metal, so keep a dedicated set of carbide burs for titanium and CoCr.

Compatibility

These burs are compatible with Amann Girrbach Ceramill milling units used for titanium and CoCr. Ceramill units do not all use the same collet and shank size, so before you order, check the collet size and the tool table of your machine and make sure they match these burs.

These are Eagle-brand burs made to fit Ceramill mills; they are not original Amann Girrbach tools. Register each new bur in your software as you would any replacement tool and reset its usage time.

Coolant and Strategy

Mill titanium and CoCr with the coolant and metal strategy your Ceramill unit and blank manufacturer specify. Heat dulls the cutting edge faster and can leave smeared or burred surfaces, so keep the coolant clean and at the right level, and do not run metal jobs with a strategy meant for other materials.

When to Replace a Titanium Milling Bur

Bur life depends on the metal, blank height, strategy and the amount of detail in each job, so there is no fixed unit count. Replace the bur when you notice:

• Rougher surfaces or visible tool marks
• Burrs along edges and margins
• More noise or vibration (chatter) than usual during milling
• Milling times longer than your software estimates
• Poorer fit of bars and frameworks
• A chipped cutting edge or a tool-life warning in your software

Tips for Longer Bur Life and Better Surfaces

• Use these burs only for titanium and CoCr.
• Keep collets and tool holders free of metal chips so the bur seats straight.
• Insert each bur to the depth your machine requires, without forcing it at an angle.
• Keep a spare 1.0 mm bur, since the detail size does most of the fine work.
• Store spare burs in their packaging and never reuse a bur that was dropped.
• If surfaces get rough right after a bur change, check calibration and the coolant before replacing the tool again.

Common Problems and Bur-Related Causes

• Broken 1.0 mm bur: a worn tool kept in use, chips in the collet or a bur not seated straight.
• Chatter marks: a dull bur or a bur not seated to the correct depth.
• Burrs and rough areas: a worn cutting edge or too little coolant.
