step drill for guardrail assembly, HSS-XE, Titan-Tec coated Spiral fluted – 2 cutting 6-18mm

PRODUCT DETAILS:

• specially designed for drilling in guardrail assembly
• 12 mm step for mounting spars and spacers (extended drill step 12 mm minimizes the danger of accidental drill hole enlargement)
• 18 mm step for guardrail spars and box sections (extended drill step 18 mm for double-drilling / 2 guardrails within 1 work step)
• the stop ring prevents the step drill from slipping through while powerful working. Protects man and machine.
• step drill made of high-alloyed special steel XE + TITAN-TEC coating for maximum service life also when machining dry (cutting oil recommended, see page 1211 and following)
• cutting depth for Diameter6, 8, 10, 14, 16 = 4 mm
• cutting depth for Diameter12, 18 = 6 mm
• 3-Flat shank (excellent torque transmission, no slippage in the drill chuck, this results to superior cutting output)

Advantages:

• significant cost reduction for drilling fully galvanized materials
• optimall cutting behavior due to constant cutting angles
• No tilting of the drill during the cutting process, therefore no wirst joint injuries (no accidents at work)

TITAN-TEC coating Especially for HSS-XE drills.

• Coating technology: PVD
• Micro hardness: 3500 HV0.05
• Coating material: TiAlN based
• Coating thickness: Diameter-related
• Max. operating temperature: 1000 degrees C
