“That’s not carbide, its Kryptonite!”

-a Haas Associate in California (after testing on a 7 HP Haas Lathe with the following parameters):

Material: 8620
Tool: 1” diameter Z-Carb
Results: The pocket was 1” axial depth and ½” radial depth. A competitive rougher ran 5 parts @ 4 IPM & 600 RPM But we ran the Z-Carb at 1,000 RPM and 10 IPM and the Z-Carb produced 19 parts!


“I believe in the Z-Carb!”

-a New York state distributor (after a Saturday shop visit where his customer used the Z-Carb to cut machining time down 90% and the shop owner told the tool crib attendant to ONLY order Z-Carb.)


“We just received a 60 piece Z-Carb order from our customer, who said that they were redesigning their machine fixtures and vises so that they can withstand the high feed rates of Z-Carb."

-a New York state distributor

The end-user reduced their cycle time to just 35 minutes by slotting with a ¾” Z-Carb in Hastalloy B2. The depth of cut was .600!


“My end user was ‘high-fiving’ me as he thanked me for introducing Z-Carb!” 

-a Pennsylvania distributor (After another successful test with the following parameters):

Material: Hastalloy
Tool: ¼” Z-Carb with 3/16” depth of cut
Results: The Z-Carb was tested against a competitive tool by running at 1250 RPM and 6 IPM. The competitive tool lasted for only 6 parts with a 4 minute cycle time. The Z-Carb lasted for 20 parts and cycle time was 1:28 seconds.


“Wow, you weren’t kidding, this tool just kicks a**!”

-an Ohio distributor


”I received a call today from an end-user in
Michigan near Detroit. The gentleman saw Z-Carb perform and was so impressed he wanted to know
if there were any possibilities he could invest money in SGS. Pretty flattering!”

-SGS President and C.O.O.


"We have sold out of all the ¼” Z-Carbs and have placed another order for more ¼” Z-Carbs. Additionally, we've sold half of our stock on the ½”
as well. We successfully tested the Z-Carb into mold shops and they worked so well that we told some of our colleagues in other shops and have picked up
new business there."

-a Florida distributor


“As a result of this Z-Carb, I feel like I have a new salesman!”

-a Pennsylvania distributor
