Kennametal 3885846 Series B707A-FBL Screw Machine Drill Bit, 11.11 mm (0.4374) Dia, 180 deg, Solid Carbide, 102.00 mm, Right Hand Cut

Features:

• Flat bottom drill with through coolant.
• Application-specific SC drill that combines two operations in one:
  • Eliminates the 180° end mill in flat-bottom drilling or when preparing an inclined or curved surface for drilling.
  • After full cylindrical engagement, the drill runs at normal solid carbide drilling parameters.
• Unique FB drill-point design with two effective cutting edges over center enable high feed rates.
• Creates a true flat-bottom hole from O.D. to center.
• Four-margin land design improves hole straightness and roundness and provides good alignment, even when drilling cross holes.
• Composition: Monolayer PVD AlTiN coated fine-grain carbide with superior surface finish.
• Screw Machine Drill Bit: 11.11 mm (0.4374) Dia, 180 deg, Solid Carbide
• AlTiN Finish, 102.00 mm OAL, Right Hand Cut, 2 Flute, Regular Spiral Flute, Straight-Cylindrical Shank, Coolant Through, Series B707A-FBL

Application:

• First choice for stainless steel and high-temperature-resistant materials. The coating offers high hardness and excellent wear resistance, as well as enhanced high-temperature properties increasing its applicability also to MQL machining of steel.
