VP15TF

aThrough coolant holes, flute geometry and cutting edge geometry are optimised for deep micro hole drilling.

aLong tool life MIRACLE® coated VP15TF

Features of VP15TF

MIRACLE® coated VP15TF is ideal for drilling due to its high resistance to chip welding. Suitable for machining a wide range of workpiece materials from mild and alloy steels through to stainless steel and cast iron.

Solid Carbide Drill with Through Coolant HolesWSTAR DRILL SERIES

Smoother flute surface for improved chip disposal.

Stability as the drill engages the pilot hole from the centre after the shoulder is guided into the hole.

Unstable because the drill shoulder is not supported in the pilot hole.

Internal coolant type for high efficiency pilot hole drilling.

The point angle is specially designed so that ø0.5 - 2.95 MWS-LB/XB/DB type drills can engage with the pilot hole from the centre cutting edge.

Cautions for usea

a

Please use a fine mesh filter (mesh<3!m) for coolant to prevent jamming in the oil hole.For deep drilling with the long type drill, machining a pilot hole is recommended. (Otherwise, centrifugal forces may cause drill breakage.)



1) Small particles of swarf will jam in the oil hole of small diameter drills. Always use a fine mesh filter as a preventative measure.

2) Dirt and dust particles adhere to the oil in old coolant and prevent an efficient flow. Regular coolant exchange is recommended.

Recommended coolant pressure: > 3MpaAt least 1.5Mpa is required.

Interruped Drilling

zUse the SB type drill.xEnsure a high precision hole is drilled for the guide.cDrill depth : Approx 1D.

zPenetrate the pilot hole at a low revolution. (Revolution speed 1000min-1, feed rate 0.2─0.3mm/rev)

xStop the long type drill 0.5─1.0mm short of the pilot hole bottom.

zStart cutting at the recommended speed and feed with a non-peck (continuous feed) cycle.

zAfter drilling, lower the cutting revolution about 0.5─1.0mm short of the hole end. (Revolution speed of around 1000min-1)

xRetract the drill to the pilot hole depth starting point at a feed rate of 3000mm/min.

cFinally clear the hole at a cutting speed of 20─30m/min and feed rate of 0.2─0.3mm/rev.

zUse a drill with a larger (flatter) point angle than the long type. The MWS-SB type is recommended.

xEnsure a high precision hole is drilled for the guide.cDrill depth : Approx 1D.

zMachine a flat on the irregular face by using an end mill or slot drill capable of spot facing. Make the spot face diameter the same size as the required deep hole diameter.

zPenetrate the pilot hole at a low revolution. (Revolution speed 1000min-1, feed rate 0.2─0.3mm/rev)

xStop the long type drill 0.5─1.0mm short of the pilot hole bottom.

zStart cutting at the recommended speed and feed with a non-peck (continuous feed) cycle.

zWhen breaking through, the cutting edge can be damaged.xFeed rate should be half the normal feed.

zRetract the drill to the pilot hole depth starting point at a feed rate of 3000mm/min.

xFinally clear the hole at a revolution speed of 1000min-1 and feed rate of 0.2─0.3mm/rev.

For Your SafetyaDon't handle inserts and chips without gloves. aPlease machine within the recommended application range and exchange expired tools with new ones in advance of breakage. aPlease use safety covers and wear safety glasses. aWhen using compounded cutting oils, please take fire precautions. aWhen using rotating tools, please make a trial run to check run-out, vibration and abnormal sounds etc. aGrinding or heating of cutting tools produces dust and mist. Inhaling large amount of dust or contacting with eyes and skins may harm your body.
