JINSHIBA Spade Drill Bit Set 6 Piece

This set contains six carbon steel spade bits with a titanium coating for durability. The flat paddle design features a sharp cutting edge to produce smooth, neat holes in wood. A self-centering spade head allows precise starting and fast drilling with quick chip ejection. The 1/4-inch hex shank fits most standard drill chucks for quick changes.

Titanium coating and self-centering spade head

The titanium coating on the carbon steel construction is heat treated to extend bit life during repetitive drilling. The self-centering tip removes the need for a centre punch, letting you start holes accurately on contact. As the bit cuts, the flat paddle geometry clears chips rapidly to maintain speed and reduce binding. These features combine to deliver cleaner holes with less effort across the included sizes.

Woodworkers needing multiple hole diameters

This six-piece set covers 10, 13, 16, 19, 22 and 25 millimetre diameters, suiting tradespeople and DIYers who frequently drill various large holes in timber, fiberglass, PVC or aluminium. The universal hex shank works with most drill brands on the market. Buyers who only need a single size or prefer auger bits for deep, clean bores should look at individual bits or alternative bit types instead.

Questions about this item

How often will the titanium coating on the 10mm to 25mm bits need re-sharpening?

The carbon steel bits are heat treated and titanium coated for durability; sharpening frequency depends on material hardness and usage intensity.

What limits continuous drilling speed across the 10mm to 25mm sizes?

The self-centering spade head and chip-clearing paddle design set the practical feed rate; larger diameters like 25mm remove more material per revolution.

How hot do the 10mm to 25mm bits get during all-day wood drilling?

Titanium coating reduces friction heat; heat buildup stays manageable with periodic withdrawal to clear chips, especially on 22mm and 25mm holes.
