Part No: D1010400  |  Barcode: 9311963000732  |  Series: D101 Silver Bullet

The Sutton D1010400 is a 4.00mm HSS metric drill from the long-running Silver Bullet D101 series — the classic Australian-made general-purpose jobber drill. M2 high-speed steel ground to a 118° standard point and a precision parallel shank, sized to DIN 338 metric tap drill standards.

Key Features & Benefits

• 4.00mm cut to DIN 338 metric tolerance — sized to engineering precision so the hole comes out exactly to dimension. Important for tap drilling where the hole diameter directly determines thread engagement.
• 118° standard point — the classic general-purpose drill geometry. Forgiving in mild steel, easy to resharpen on a standard drill grinder, and works in a wide range of materials without point modification.
• M2 high-speed steel — the standard tough tool steel for general engineering. Holds an edge through repeated drilling without backing off, and resharpens easily when it does dull.
• Precision parallel shank — the shank diameter equals the cutting flute diameter to within tight tolerance, so the drill runs concentric in any 3-jaw chuck.
• Bright finish — clean low-friction surface that takes cutting fluid well in metals and doesn’t pick up gummy residue in aluminium.
• Sutton Australian engineering — the D101 Silver Bullet has been the Australian workshop default for decades; consistent point geometry batch to batch, made by Sutton Tools in Thomastown.
