Ball Nose Finisher Cutter Bodies

Standard Shank End Mills (standard ball nose, carbide core)
Oversized Shank End Mills (standard ball nose, carbide core)
Solid Carbide End Mills
Undersized Shank End Mills for instant clearance
Back Draft & Flat Bottom End Mills
Screw-On Modular Heads & Modular Extensions
Metric Series Ball Nose Cutter Bodies & Inserts
Thru-Coolant Cutter Bodies have been removed from our product line, providing you with a more solid cutting tool yielding maximum rigidity. Customers requiring thru-coolant tooling can still receive this option, but on an "upon request" basis only.

* Note: All Dapra Ball Nose end mills accept either inch or metric inserts of like sizes.
Example: BNEM0750 and GWR20 accept either a 3/4" or 20mm diameter insert.
BNEM0500 and GWR12 accept either a 1/2" or 12mm diameter insert.

Solid Carbide End Mills

Achieve Maximum Performance with Carbide Cutter Bodies!

Optimize performance with Carbide Shank tooling:

Reduced deflection
Increased stiffness
Less chatter
Heat shrink toolholding capability (Ball Nose with Solid Carbide Shank only)

* Keep brazed joint a minimum of 2" away from heat shrink toolholder.
SC (Solid Carbide Shank) tooling is suitable for FINISHING APPLICATIONS ONLY.
SC tooling is NOT suitable for roughing and applications with significant heat.

Screw-On Modular Heads & Modular Extensions NEW Dapra's Carbide Core Modular Extensions Are Ideal for Standard Inch End Mill Holders

Standard inch shanks, providing adaptation for end mill holders, milling chucks and heat-shrink holders
3 sizes to accommodate modular head sizes from 3/4" to 1-1/2"
Carbide core for enhanced vibration dampening capability; reduced deflection and improved rigidity
Optional add-on extensions for additional 2" reach – screw on to base extensions (for 3/4" to 1-1/2" modular heads)

Dapra's Line of Screw-On Heads Fits Industry Standard Cutting Systems

Compatible with ISO standard modular cutting systems
Close-tolerance mounting of heads minimizes runout and maximizes rigidity
Provide significantly more effective reach than solid end mills
Use standard inch wrench flats, no special metric wrenches needed

Dapra's Modular Extensions Provide Even More Cutting Options

Made of high-density tungsten, providing extra resistance to deflection and chatter
Machined on both ends; can be cut in half and used with two different modular heads
Metric shank diameter provides clearance for each inch size modular head
