In the case of the single-lip deep drilling tool, the cooling lubricant is supplied through the cooling channel integrated in the tool and simultaneously removed with the chips through the v-shaped groove of the drill shaft. Single-fluted deep hole drills can be used for holes with a bore diameter of 0.5 to approximately 113.99 mm.
For this deep drilling method, the coolant must be pumped through the cutting edge of the drills with sufficient pressure and exits again at the cutting head. Single-lip deep hole drilling with the single-lip drill can only be realized if a high pressure can be generated for the cooling lubricant during drilling.
