JET 671908 Socket Extension Bar, 3/8 in, 10 in OAL

• These bits feature razor sharp 135 deg split point self-centering tips, eliminating "walking" and the need for center punching and penetrate on contact
• The superior bronze oxide (gold) ground flute finish reduces friction, allowing outstanding drilling performance with less operator pressure
• Special flute form enhances chip ejection, reduces drill retractions (wood peckering) and improves coolant flow to the tip
• Heavy duty, high molybdenum steel offers greater strength and rigidity, longer lasting cutting edges and improved hole tolerances, permitting higher feed rates
• Greatly reduces chuck and shank damage and increases cutting efficiency
• Drill up to 4X faster and last up to 7X longer than regular drill bits in steel, stainless steel and alloy steel applications
• JET-KUT GOLD drill bits are the most advanced drill bits available in the Canadian market
• JET offers the TORQUE DRIVE three flat shank for chuck to bit gripping power that is unparalleled in the industry (available on 3/16 in diameter and larger bits)
