Introducing our new suite of indexable drills, built for long use and accurate drilling into steel, stainless steel and exotic materials. A truly balanced, high-performance tool, the HID requires only one insert type for both pockets—an innovation that delivers added efficiency. The HID features a hardened, cool-ant through high-quality drill body, and is available in a wide range of diameters and lengths.

GP Chipbreaker HID 90° Insert Rotation

Most comparable indexable drills use different inserts for the inner and outer pockets, which can create confusion and misapplication among machine operators.

1 Insert — 4 Cutting Edges — for Both PocketsA truly balanced tool, the Hertel Indexable Drill was designed to deliver equal cutting pressure for both outboard and inboard inserts. So one insert works on both. This means you only have to stock one type of our General Purpose chipbreaker. When a cutting surface is worn, just flip or rotate the interchangeable insert—each one has four cutting edges.

HP130D Insert Grade for Excellent Wear and Adhesion ResistanceOur HP130D grade delivers great performance when applied to steel, stainless steel and exotic materials. The Hertel PVD-coated cutting edge is composed of nanometer thick layers of TiAlN (titanium aluminum nitride) and AlCrN (aluminum chromium nitride), which offer excellent heat and wear resistance.

Cutting Forces

VERSUS

Balanced HID Conventional Drill

Accuracy: Precise Holes, Stable Drilling, Lower Cutting ForcesThe HID offers a better-balanced cutting action with smoother ease of entry and exit than other indexable drills. The balanced cutting action is achieved by positioning the inserts in the pockets to allow the outer edges of the inserts to operate under similar cutting forces.

HID Conventional Drill

Flat-Bottom SurfaceThe HID delivers a flatter bottom than comparable drills. If flat finishing is necessary, an HID hole leaves you far less material to remove on the bottom surface.

Example:

When making a .787" blind hole, the bottom of the HID hole is dramatically flatter than a comparable industry competitor. In fact, ours is approximately .055" flatter. HID = .016" material for flat finishing Competitor = .0705"


Machining Centers

The HID delivers through and blind holes with coolant at production capacity, with increased tool body life. Having only one insert style eliminates operator errors when indexing.

Lathes

In a turning application, the HID drill can be used to plunge directly into the face of a part; once the hole is drilled, it can then be offset and bored to a larger diameter. When used on the outside diameter, it can turn a shoulder or bring a part to final size all the way around.

Maximum Boring Offset = 3% of Drill DiameterExamples:

0.750" drill + 3% max offset = 0.0225" 1.250" drill + 3% max offset = 0.0375" 1.750" drill + 3% max offset = 0.0525"

Offset Technical DataWhen used on a lathe, it is important not to exceed 3% of the drill diameter when offsetting. The offset can be used to gain additional inside diameter or even used to turn the outside diameter of a part to a smaller diameter.

Drill/Offset and BoreThe HID drill can be used in both lathes and machining centers.

Additional CapabilitiesBeyond through and blind holes, specialty applications include drilling directly into a slanted surface, boring, counterboring, core drilling, over drilling, drilling half-round holes in the side of a part, and outside-diameter turning. Caution needs to be applied when drilling stacked plates, due to breakthrough. When boring, only forward feeding may be applied.

Technical InformationThe HID performs optimally under increasingly demanding conditions with each hole, producing the best chips at the most aggressive parameters. The layered AlCrN / TiAlN coating demonstrates superior performance under increased heat and cutting pressure.
