80290 Type 190-ALN HSS 135Â degree Split Point NAS 907B TiAIN Coated Jobber Length Drill Bit (6 pack) 3000 Neoprene Lead-Ins are constructed of

Neoprene Lead-Ins are constructed of oil-resistant neoprene rubber hose

the CUCSHA has a Hard Chrome bearing insert and a Stainless Steel housing

Reduces Friction and Wear to Tooling

• Nitride process diffuses nitrogen into the surface to create a case hardening resulting in superior tool life and exceptional corrosion resistance

Operating Temperature 5 - 230°F (-15 to 110 °C)

80290 Type 190-ALN HSS 135Â degree Split Point NAS 907B TiAIN Coated Jobber Length Drill Bit (6 pack) 3000 Neoprene Lead-Ins are constructed ofHeavy duty construction for drilling in tougher materials Manufactured from premium high speed steel 135 split point is self centering for reducing thrust and easier penetration Provides exceptional oxidation resistance and extreme hardness TiCN is harder and has a lower coefficient of friction then TiN coating. Recommended where moderate temperatures are generated. Manufactured to NAS 907B aerospace specification Titanium aluminum nitride (TiAIN)
