For Higher Speed and Higher Precision !
|
|
Twist V drills with oil holes are essential tools for better hole making jobs.
our factory (Omi) opens the new era by supplying a variety of standardized drills with structure and function which are best suited for IT (Information Technology) and FA (Factory Automation) industries.

|
High-Speed Mechaning
|
|
We offers modem drills with oil holes, which provide customers with High-Speed spindle revolution ranging from 8,000 to 20,000 rpm and fast feedrates raning from 0.1mm/rev to 0.4mm/rev to reduce machining time.
|
|
|
|
Machining Accuracy
|
|
Machining accuracies are listed as highly precise levels of H7 diametral accuracy and of 3S surface roughness. Improved oil-hole lubricating characteristics, deep-hole making straightness accuracy are realized.
|
|
|
|
Tool Life
|
|
V-Drill's unique flute shape serving as a self-guide, has 6 flutes of over 5mm diam. and 4 flutes of less 5mm diam., and it ensures enhanced staigtness as well as longer tool life by reducing the number of tool changing tasks.
|
|
|
|
Reduction of Cutting Force
|
|
V-Drill's has a configuration of 2 rough-cut flutes and 4 finish-cut flutes totalling 6 flutes with a right flute/15°right helix angle, along with high toughness by enlarging flute core thichness, permitting better balanced machining as well as stable machining by reducing cutting force.

V Drills ( Drilling and Reaming in a single pass machining)
|
|
H7 hole accuracy and 3S surface roughness in a single pass machining.

For Higher Accuracy and Productivity
|
|
Drills and Remaers are the essential tools for better hols making. We have been contributing to the industries by supplying various types tools. We, hole making specialist, opens the new rea with "T.C. V-Drill".
|
|
|
|
One Pass to Finishing
|
|
3 processes, Rough → Semifinish → Finish can be completed in one pass of the tool, so shorter production process, lower cost, and less scrap rate can be obtained
|
|
|
|
High Hole Accuracy
|
|
Highest Accuracy of H7 and surface roughness of 3S can be obtained. Hole straightness can be 1/3 〜 1/5 of those obtainable with regular twist drills and thrust force same as regular twist drills.
|
|
|
|
Faster Feed and Longer Life
|
|
This newly developed cutting edge configuration enables the tool to smoothly cut into material and to feed faster and still to have longer life.
|
|
|
|
Combined Machining
|
|
Combination of chamfering, couterboring, and spot facing can be completed in single pass. As cutting chips will not curl, the tool is best suited in the automation process. The max. hole depth that can be drilled is about 5times of the tool diameter.

V Drill / Burnishing Drill Comparison
|
|
|
|
■V Drill |
|
■Burnishing Drill |
|
1)
6 blades (5mm or greater), 2-stage cutting
method (rouhening / cutting edges)
2) Equipped with a jump blade (roughening /
cutting edges) that attracts very little
adhesion on the built-up edge. This helps to
limit negative influences on the roughening of
holes so that stable machining can be
continuously performed.
Thanks to this groove,
machining oil can easily adhere to the blade
tip, which greatly reduces any negative
influences on the roughness of the hole surface.
3) Uses 6 blades (5mm or greater) and an uneven
split jump configuration to provide finished
hole surfaces with excellent roughness and
roundness that can be maintained for a long
time.
4) The jump configuration helps to greatly
extend the life of the tool. In fact, the
standard tool life is the equivalent to the
machining of at least 10,000 holes.
5) The jump configuration allows for greater
feed speeds (0.3mm/rev), which help to reduce
the processing time. |
|
1)
Only 4 blades. Uses a simultaneous cutting
method that performs roughening and cutting at
the same time.
2) There is a large amount of adhesion on the
built-up edge, which has a negative influence on
the roughening of holes. This means that stable
processing is not possible and the users will
have to worry about producing faulty work.
Shavings become adhered to
this section, which hurts the quality of the
hole surface roughness.
3) Uses an even edged blade that pushes outward
to roundness is poor and it is difficult to
maintain the hole.
4) Tool life is rather unpredictable because
this pushing outwark type blade is used. In many
cases the blades will need to be re-sharpened
somewhere between 1,000 and 3,000 holes.
5) Hole finishing and surface roughening cannot
be maintained unless the feed speed is less than
0.1/rev. |
