DAPRA's New RHINO-FEED™ Line Allows Feed Rates Up to 5x Faster Than Normal
DAPRA Corporation is pleased to announce RHINO-FEED™: a new line of high-feed cutters and inserts that takes advantage of chip thinning to allow feed rates up to five times faster than normal.
High-feed milling creates significant chip thinning due to an extreme lead angle. The RHINO-FEED system adjusts feed rates to compensate for this condition and provides very high feeds, at lighter depths of cut. RHINO-FEED can help maximize productivity in advanced applications such as mold cavity and core roughing, pocketing, roughing of complex part contours and helical interpolation.

HFDEH Inserts
New HFDEH RHINO-CARB high-feed, CNC-pressed Toroid inserts from DAPRA are designed for very aggressive metal cutting and long tool life. HFDEH inserts are for use with all R4 designated Toroid cutters (1/2" IC insert).
HFDEH inserts are designed to fit current Toroid cutter bodies and provide very high metal removal rates at lighter depths of cut. They have a positive geometry, designed to provide good chip formation and lower cutting forces in steels, stainless steels, and high-temperature alloys. Available in all tougher Toroid substrates: DMK30, DMK25 and DMP25.

New DMK30 Insert Grade
DMK30 – Dapra's newest XPET insert substrate – features a micro-grain structure with medium cobalt content, providing very good edge strength and wear resistance while maintaining outstanding toughness. DMK30 was formulated for high-performance applications involving tool steels, austenitic stainless steels and most high-temperature alloys.

New RHINO-CARB "N" Cutting Edge
Dapra has expanded its popular Toroid RHINO-CARB CNC-pressed insert line with a new N cutting geometry for round and octagonal inserts. The new N inserts provide smoother cutting action for steels, irons and many stainless steels when compared to the stronger T insert edge. The N offers a higher-positive edge preparation and rake angle than the T, providing excellent cutting action that creates less heat and pressure than the T while offering greater strength than the very high-positive D.
| Cutting Edge | Edge Strength | Tool Pressure | Heat Creation |
|---|---|---|---|
| T (T-Land) | Strongest | Highest | Highest |
| N (Neutral) | Strong | Medium | Medium |
| D (Dished) | Medium | Lowest | Lowest |
Use Dapra's T geometry where the heaviest cuts are taken, or where vibration or chatter may be causing edge damage. This geometry is suitable for steels, irons and 400-series stainless.
Use Dapra's N geometry in typical cutting applications where high-performance milling of steels, irons and 400-series stainless is desired.
Use Dapra's D geometry in applications where the lowest tool pressure and higher shear are required. This geometry is best for most stainless steels and high-temperature alloys, but it is also a very free-cutting performer in softer steels.
New DMK25 Insert Grade
Our newest substrate is called DMK25. It features a micro-grain structure with a medium cobalt content, providing very good edge strength and wear resistance while maintaining outstanding toughness. DMK25 was formulated for applications involving tool steels, austenitic stainless steels and most high-temperature alloys. DMK25 is available in our D geometry as well as the new N (see above), but will not be available in T. It will be available in each of our high-performance coatings:
- DMK25-GLH (Premium AlTiN)
- DMK257 (basic AlTiN)
- DMK25-HP (Premium AlCrN)
- DMK253 (TiCN)
Helical Cutting Edge Ball Nose Inserts in Metric Sizes
Dapra's advanced HBN Ball Nose inserts with helical cutting edge are now available in metric sizes ranging from 10mm to 32mm in diameter. The HBN inserts' helical cutting edge optimizes performance in Ball Nose finishing applications, offering smoother cutting action, reducing chatter and providing a cleaner surface finish. The HBN geometry is capable of heavier cutting and increased metal removal while lowering stress on work materials. Another advantage of the helical cutting edge is the longer tool life that results from reduced tool pressure and heat generation. Click here for details on our Metric Ball Nose line.
New Carbide Core Extensions Improve Rigidity, Extend the Reach of Modular Heads
Dapra is pleased to announce a new line of Carbide Core Modular Extensions to complement our existing Modular Heads and Extensions. These extensions feature:
- Weldon shanks in standard inch sizes – ideal for standard end mill 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)
Self-Centering Vise for Universal Machining
Dapra has introduced a new line of self-centering vises for universal machining. Two models, the SC-125 (4.9" / 125mm wide) and the smaller SC-090 (3.9" / 90mm wide), are specifically designed to meet the demands of workholding on 5-axis milling machines. The new high-precision vises are compact, tall and self-centering. Parts are being held high above the vise bed, which gives the machine tool spindle access to virtually all sides of a workpiece. The self-centering feature allows all coordinates of the workpiece to be programmed from a common reference point. Click here for details.
New RHINO-CARB™ Toroid Inserts Provide Ultra-Aggressive Metal Cutting and Longer Tool Life
DAPRA is pleased to announce the introduction of RHINO-CARB, a full line of high-performance CNC-pressed Toroid inserts. Designed for aggressive metal cutting and long tool life, these thicker inserts offer greater strength and enhanced heat absorption capabilities. A positive top rake reduces cutting forces and torque, while a stronger cutting edge accommodates heavier chiploads and provides greater shock absorption. This new insert line fits current DAPRA Toroid end mills and shell mills with the aid of a thicker top clamp. Pressed round ("button") inserts, octagonal inserts, square inserts and high-feed inserts are available in sizes from 3/8" to 3/4" I.C. Click here for details on our full Toroid line.
The Allmatic TITAN 125: DAPRA's Most Versatile High-Pressure Vise
The new ALLMATIC TITAN 125 high-pressure vise is so versatile that, according to ALLMATIC, "Nothing is beyond its grasp!" Combining almost all of the functions of the popular ALLMATIC NC and T-REX, the TITAN 125 has all of the precision and versatility required of today's workholding tools. It has a robust GGG 60 base with hardened and ground guideways to provide a high level of accuracy and excellent wear resistance. The large side openings allow chips and cooling lubricant to escape. Threaded holes on both sides allow for the attachment of workpiece stops, and precise aligning slots in the base ensure smooth handling. Other benefits of the TITAN 125 include short set-up times, without an external power supply, and the capability to change workpieces in a matter of seconds.

High-Feed Inserts Enhance Roughing Capabilities for Small-Diameter Applications
Dapra has introduced a new series of High-Feed inserts that are ideal for smaller-diameter applications. The HFBD Series Inserts are designed for outstanding metal removal rates when used with Dapra's BNEM Cutter Bodies for high-feed roughing, pocketing, cavity/core roughing and helical interpolation. Available in 3/8" through 3/4" diameters, these versatile cutters are furnished in medium-temperature and high-temperature grades. A further advantage of the HFBD Inserts is their eligibility for Dapra's Ball Nose Replacement Program, through which the buyer can receive FREE and Discounted replacement Ball Nose Cutters for every 30 Inserts purchased. In addition to the new Inserts, Dapra has recently announced the availability of 3/4" and 1" Solid Carbide Ball Nose Cutter Bodies.
T-REX Allmatic Vise with Adjustable Gripper Studs
Dapra's Allmatic Precision Machine Vise line has been expanded to include the new T-REX Vise. The T-REX features adjustable gripper studs that are embedded into the workpiece, ensuring safe and quick clamping of raw parts, thermal cut parts and sawn off material. The T-REX is suitable for materials with a strength value of approximately 900 N/mm2 (with the exception of hardened materials), and features a movable pivot jaw to accommodate different workpiece shapes. The T-REX is easy to operate with a mechanical power intensifier. Click here for more details on the T-REX, or here to view our entire selection of Allmatic clamping systems.
