High Speed, High Efficiency Machining 

Every coolant groove of the OIL-S-XPF is designed with a coolant hole in order to attain 

superior lubrication and improve internal cooling. This feature enables higher speeds, 

efficiency and durability, resulting in maximum cost performance. 

Ecological & Economical 

In addition to reducing CO 2 

through high efficiency machining, the S-XPF has also 

minimized environmental impact by enabling users to machine with internally-fed, 

chlorine-free, water-soluble coolant, as well as through minimum quantity lubrication 

(MQL). These reductions are beneficial to the environment and are economical 

because electrical consumption, coolant purchase and disposal expenses are also 

minimized.

The OIL-S-XPF tapped over 500 holes in 

1045 Steel, while the competitor's cut tap 

only achieved 12 holes before chipping. 

Typically, thread forming is very difficult for 

larger threads (over 3/4" or M20) because 

of extremely high tapping torque, friction 

and machine power requirements, but 

the OIL-S-XPF reduced tapping torque and 

friction, and kept the machine spindle load 

below 11.4 hp, making the OIL-S-XPF ideal 

for large threads and other extreme tapping 

applications.

Here is an example of water-soluble coolant machining using 

OIL-S-XPF containing coolant holes. It tapped approximately 

2,000 holes in 4140 (35 HRC). Ordinarily, externally-fed 

coolant on horizontal machining centers results in poor

17x the Durability of Cutting Taps! 

The S-XPF is a superior thread-forming tap that stably makes threads 

without creating cutting chips. Its adoption rate in nonferrous materials 

is approximately 90%, in terms of the number of machined holes. In 

contrast, its diffusion rate in steel materials is 20% (per OSG data). The 

S-XPF is a new type of thread-rolling tap that eliminates the obstacles 

associated with thread-forming when tapping in steel materials. 

Expands the Range of 

Thread-Rolling Taps 

The S-XPF has significantly reduced friction resistance by adopting a special threading design and a special surface treatment. This 

results in a reduction in torque of 40% from the traditional product and a considerable suppression of heat generation (see example 

below)! It facilitates previously difficult applications such as 40 HRC steel materials and thread-forming of large diameters, and 

enables high-speed operation using water-soluble coolant while attaining an even longer tool life. 

• Reduces machining torque for use in low-lubrication environments.

Even when using small-diameter taps with 

chlorine-free water-soluble coolant, the S-XPF 

is able to achieve a "definite performance 

improvement" and "stable tapping of high 

hardness (35HRC) material." As the thread 

size increases, the disparity between the 

S-XPF and the traditional product becomes 

obvious due to the increase in the amount of 

plastic deformation and resulting changes in 

the amount of generated heat.

On horizontal machining centers, tapping deep holes properly is considered difficult due to the insufficient feeding of coolant in the work area. However, the 

S-XPF has solved this problem and has succeeded in attaining superior performance. The outstanding durability of the S-XPF is clearly demonstrated in this 

type of operation.

The competitor's product could tap only 500 to 700 holes using a coolant that is highly 

diluted to five times. In contrast, the S-XPF could tap over 1,300 holes, successfully 

reducing costs. This cost reduction can also be applied to reducing the running cost of 

the coolant by increasing its dilution rate. The S-XPF can offer many ideas to optimize 

your work on the shop floor!
