C-Series 304 Stainless Steel Cannula:

All 304 stainless steel drills are produced from full hard tubing with cutting edges machined and sharpened for maximum consistency. Relatively inexpensive, C-Series stainless steel yields extremely sharp edges and is available in a range of gauge sizes. These sizes can be further modified to provide many inside diameters, wall thicknesses and tip configurations. This series is typically used for holes as small as .005" diameter. Resultant hole diameter from any size drill varies with durometer of material being processed and the methods used. Listed hole sizes are an approximate guideline. Standard overall drill length is 1 1/2".
Cutters for Braided Tubing:

M-Series hole cutters use tungsten molybdenum tool steel with a high performance combination of hardness (65 Rockwell C), toughness and wear resistance. It's an ideal material for specialized applications like hard or braided tubing.
H-Series Furnace Hardened 17-4 Stainless Steel Core Drills and Punches:

H-Series punches and drills are machined from solid, centerless ground bar stock and furnace hardened for maximum durability. This iron-chromium-nickel alloy couples high corrosion resistance with heat-treat capability for high strength.

Round sizes over .015" diameter can be manufactured along with oval punches in most any combination of oval length and width.

Cutting edges at the tip O.D., I.D. or somewhere in between meet most catheter hole making applications. Many sizes are in stock. Call for recommendations.

17-4 Stainless Steel Round Hole Drills

Machined from solid, centerless ground 17-4 stainless steel and furnaced hardened. Available in most sizes from .015" to .500" in increments of just a few thousandths of an inch. Several styles of cutting edges are available. Standard tip length is equivalent to the drills shank diameter. Standard overall length is 1 inch. (25.4mm)

17-4 Stainless Steel Skiving Drills

Furnaced hardened 17-4 stainless steel skiving drills are designed to cut chips from the side of a catheter leaving an oblong hole often used to access lumens in multi-lumen tubings. The cutting edge is at the O.D. and there is no through hole in the shank. Special combinations of shank and cutting edge diameters are quoted upon request.

T-Series Stainless Steel:

This cutlery-grade stainless steel can be heat-treated to a higher hardness level (60 Rockwell C) than any other grade of corrosion-resistant stainless. Extreme abrasion and wear resistance make it the practical choice for high-volume production machines.
