Kennametal 3867876 Extra Length Drill Bit, Letter E (1/4"), 135 deg Point, Solid Carbide, 214 mm Flute Length

Features:

• HP solid carbide deep-hole drill with through coolant for steel, cast iron, stainless steel, high-temperature alloys, and non-ferrous materials.
• Application-specific SC drill for drilling holes up to 30 x D up to 4x faster than conventional HSS and gun drills.
• Broadest diameter range on the market from .0938 - .6299″ (2,383 - 16 mm).
• KMH-point geometry is available as a semi-standard, especially for crankshaft applications.
• KN25 Beyond uncoated grade (B27_HPS) with highly polished surface ensures superior chip evacuation and prevent built-up edge in aluminum and high-temp alloys, even when low-pressure coolant or MQL is applied.
• Composition: Uncoated, highly wear-resistant ultra-fine-grain carbide.

Application:

• Highly polished chip flute surface ensures superior chip evacuation and reduces tendency for built-up edge. First choice for deep-hole drilling of non-ferrous materials.
