The Sutton D126 Blue Bullet panel drill is a single-ended HSS drill with a blue steam-oxide finish, a 118° Form C stub point and a rigid design for through-hole drilling. It is made for rivet holes in sheet metal fabrication, in 3 sizes from Ø3.26 mm to Ø4.85 mm.

Panel drills are for shallow holes no deeper than 1-1/4 × the drill diameter (d1). Supplied in packs of 10.

Where this product is used

• Rivet holes in sheet metal fabrication, flat and curved panels.
• Through-hole drilling in thin material, within the 1-1/4 × d1 depth limit.
• Designation: Ferrous Materials.
• Materials rated Optimal: non-alloy steel, about 0.15 %C, annealed; non-alloy steel, about 0.45 %C, annealed; non-alloy steel, about 0.45 %C, quenched and tempered (250 HB); and low-alloy steel (under 5% alloying elements), annealed.
• Also rated Effective: non-alloy steel, about 0.75 %C (annealed and quenched and tempered) (some grades); low-alloy steel, quenched and tempered (275 to 350 HB) (some grades); high-alloy and tool steel; austenitic stainless steel; duplex stainless steel; grey cast iron (some grades); nodular cast iron (some grades); and chilled cast iron.

Finish

Blue (steam oxide). The blue steam-oxide finish is for ferrous metals: it helps prevent chip build-up on the cutting edges (especially in carbon steels), the oxide layer protects the surface and it carries lubricant well.

Sizes and rivet sizes

Each size is matched to the rivet it suits. Sizes in this range:

Accuracy

Sutton drills are ground to an h8 diameter tolerance (nominal or smaller, never larger).
