Description
7700 Series Half Mask Respirators, Medium ORS NASCO Evolution standard geometry is sufficient Evolution standard geometry is sufficient for most drilling applications Manufactured specifically to maximize hole accuracy while minimizing cutter vibration and extending annular cutter life Using this standard geometry enhances accuracy and saves time This allows for a single ejection of slugs when drilling through stacked material visible deformation provides evidence of proper closure Deburred edges reduce risk of damage to parts being clamped Provides a degree of elasticity to accommodate changes in size of the parts being joined
