Pros: T-Process strengthens the edge, helps eliminate chipping and gives a smooth edge.
Cons: T-Process will bring up a burr in certain materials, and it is not for materials that like a sharp edge, such as aluminum and plastics.
To order a RobbJack tool with a T-Process, use the existing Part Number, and add -TP.
Example: An XG-402-16 with T-Process is Part Number:
XG-402-16-TP
See price sheet for pricing.

Pros: A Wiper Flat gives better floor finishes.
Cons: Wiper Flats will increase surface contact, not for use on thin floors. To order a RobbJack tool with a Wiper Flats, use the existing Part Number, and add -WF.
Example: An A1-201-12 with wiper flats is Part Number:
A1-201-12-WF
See price sheet for pricing.

To order RobbJack tools with Weldon Flats, use the existing Part Number, and add -FL.
Example: An A1-201-12 with a Weldon Flat is Part Number:
A1-201-12-FL
No Charge

To order a RobbJack tool with a Full Radius (or Ball End), use the existing Part Number, and add -BN.
Example: An A1-201-12 with a Full Radius (Ball End) is Part Number:
A1-201-12-BN
See price sheet for pricing.

To order a RobbJack tool with a Corner Radius, use the existing Part Number, add -CR and desired Radius Size.
Example: An A1-201-12 with a .005 corner radius is Part Number:
A1-201-12-CR .005
See price sheet for pricing.

To order a RobbJack tool with a 45° Chamfer, use the existing Part Number, add -CH and amount of Chamfer.
Example: A1-201-12 with a .040″ 45° chamfer is Part Number:
A1-201-12-CH .040″
See price sheet for pricing.

Modify any standard tool with a neck to get the job done quickly. A neck will increase rigidity, reduce tool deflection and last longer than a long length of cut tool. Necking can be added to most standard tools in 1–2 days.
Applications:
To order a RobbJack tool with a Reach, use the existing Part Number, and add -N and the desired length from the end of the tool.
A tool necked with Feather Blend is a reduction in the tool diameter after the cutting length so the tool can cut deeper than its cutting length. It features a smooth transition from the cutting diameter to the neck diameter. Feather Blend reduces staircase marks and stress risers in parts and helps to maintain the strongest tool possible.
Example: An A1-201-12 necked with 1.0″ Reach is Part Number:
A1-201-12-N 1.0″
See price sheet for pricing.

Our edge preparation dampens vibration to help eliminate chatter.
Applications:
Our patented Mirror Edge geometry helps to eliminate chatter. This geometry can be used in any application where chatter is a problem, usually for thin walls, valves, deep pockets or where the tool sticks out more than 3:1 length to diameter ratio.
To order RobbJack tools with Mirror Edge, use the existing Part Number, and add -ME.
Example: An A1-201-12 with Mirror Edge is Part Number: A1-201-12-ME

Coolant Grooves allow coolant to flow around the outside of the tool for through-spindle coolant applications. It is a lower-cost option to through-the-tool coolant holes.
To order a RobbJack tool with a Coolant Grooves, use the existing Part Number, and add -CG.
Example: An A1-201-12 with coolant grooves is Part Number:
A1-201-12-CG
