Description
Parabolic Flute Jobber Length DrillsParabolic Flute drills feature a unique flute design that greatly enhances chip flow, coolant flow to the drill point and heat dissipation in deep hole drilling greater than three diameters deep. Recommended for drilling aluminum and other low to medium tensile strength materials.Titanium Nitride (TiN) Coating increases tool surface hardness, wear resistance, heat resistance, chip flow and resists chip welding. Enhanced hole quality at higher speeds and feeds.Country of OriginUSAWarning-Proposition 65- For Californian Users onlyWARNING:This product contains a chemical known to the State of California to cause cancer or Birth defects.For more information go towww.P65Warnings.ca.govDrill Bit Size / Cutting Diameter (DC) 7/16″Coolant Supply Property (CSP) ExternalDrill Bit Size / Cutting Diameter (DC) – Inch 7/16″Cutting Depth u200e4-1/16″Decimal Equivalent 0.4375Flute Length u200e4-1/16″Measurement Type InchPoint Shape SplitAngle 135 DegreesShank Type StraightCutting Edge Material HSSConnection Diameter Machine Side (DCONMS) 7/16″Flute Type ParabolicSeries/List 1355Coating TiNOverall Length (OAL) u200e5-1/2″
